About This Book

The narrative traces the evolution of Western art music from medieval church chant and early modal scales through the emergence of notation, harmony, and counterpoint, showing how polyphony matured in church and secular traditions. It follows developments in instrumental practice and forms—the orchestra, chamber music, sonata, opera, and piano—treating technical advances in composition and performance, fingering, touch, and pedaling, and surveys influential composers and movements from Baroque contrapuntal masters through Classical clarity to Romantic expansion and the music drama. Throughout it emphasizes structural, theoretical, and practical changes that shaped modern musical language.

[O Do-mi-ne Je-su Christ . . . . . e.]

On the whole, however, the first period of the Netherlands school was characterized by a devotion to the mechanics of music. The second period was illuminated and dominated by the famous Josquin des Prés, whose music is still heard at times, and is still ravishing to the ear. Josquin was born at Condé in or about 1450, and was a pupil of Okeghem. He was a singer in the Sistine Chapel at Rome, and on the death of Sixtus IV., in 1484, went to the court of Hercules d'Est, Duke of Ferrara. He was afterward a short time in the service of Louis XII. of France, and finally of Maximilian I., Emperor of the Netherlands, who made him provost of the Cathedral of Condé. In that town he died, on August 27, 1521. A large number of his works exists. There are in print nineteen masses, fifty secular pieces, and over one hundred and fifty motets. Josquin is the first genius in the development of music who had sufficient musical material already formulated to enable him to write freely. His works are notable for their elegance of style, and for the firm mastery of the difficult counterpoint of his time. Martin Luther, noting how he moulded seemingly inflexible material to his purpose, said, "Josquin is a master of the notes; they have to do as he wills; other composers must do as the notes will." Baini, the biographer of Palestrina, in describing the immense popularity of Josquin's compositions, says that there was "only Josquin in Italy, only Josquin in France, only Josquin in Germany; in Flanders, in Bohemia, in Hungary, in Spain, only Josquin." In its technical aspect Josquin's music presents for consideration no special feature, except that he wrote always in more than two parts. His music is notable chiefly for its pure beauty, and he was the first composer to make a determined effort to secure that. He was able to do this because his predecessors had so fully developed the technics of polyphonic writing. Josquin, however, was not without grave faults. He continued the practice of using secular airs in the mass, and wrote a mass on "L'Omme Armée." He also had the bad taste twice to set to music the genealogy of Christ, a mere catalogue of names.

The third period was very rich in masters of ability. Of Gombert little is known save that he was a pupil of Josquin. Adrian Willaert, the most brilliant light of his period, was born at Bruges in 1480, and was a pupil of either Josquin or Jean Mouton. After many changes he settled in Venice, where on Dec. 12, 1527, the doge, Andrea Gritti, appointed him chapel master of St. Mark's. He carried the teachings of the Netherlands school into Italy, became the head of a great music school, was the teacher of many noted organists, and had a profound and wide influence on musical art. Claude Goudimel was born in 1510, founded a music school in Rome, and was the teacher of the great Palestrina. He subsequently went to Paris, became a Protestant, and was killed in the massacre on St. Bartholomew's eve, Aug. 24, 1572. Cyprian di Rore was born in Brabant in 1516, and succeeded Willaert as chapel master of St. Mark's in Venice. He died in 1565. Clement Jannequin was a native of Flanders. Little is known of his life, but some of his compositions are extant. Willaert's work must first claim our attention. Finding two organs in St. Mark's he introduced antiphonal writing into the music of his time. He wrote some of his grand works for two choruses of four parts each, so that each chorus could answer the other across the church. He paid much less attention to rigid canonic style than his predecessors had done, because it was not suited to the kind of music which he felt was fitting for his church. He sought for grand, broad mass effects, which he learned could be obtained only by the employment of frequent passages in chords. So he began trying to write his counterpoint in such a way that the voice parts should often come together in successions of chords. In order to do this he was compelled to adopt the kind of chord formations still in use and the fundamental chord relations of modern music,—the tonic, dominant, and subdominant. The tonic is the chord of the key in which one is writing; the subdominant is that of the fourth note of the scale of that key; and the dominant that of the fifth, thus:—

[Tonic. Subdominant. Dominant. Tonic.]

This is the succession of chords which children strum when they try to play accompaniments on the piano. It is the simplest progression of harmony we have, and lies at the basis of all our common tunes. It is called diatonic harmony because it is formed of chords on the whole tones of the scale, in contradistinction to chromatic harmony, founded on the chords of the semitones. It is necessary to speak of chromatic harmony here, because Cyprian di Rore made a special study of it, and his "Chromatic Madrigals," published in 1544, had a great influence upon the progress of music. The old church scales were essentially diatonic, and chromatic harmonies were not practicable in music written in those scales. Di Rore's madrigals were influential in showing composers how they could write more flexibly and more beautifully by breaking the shackles of the old Gregorian scales. Still, most of the music of that time continued to be essentially diatonic, for the composers had just begun to explore the possibilities of chord modulation. These possibilities do not seem to have been exhausted even by the music of Wagner.

The development of secular music at this time was remarkable. The scientific composers began to make a practice of writing music to be used outside of the church. They wrote madrigals and other part-songs of real merit, and in them they made attempts at expression. Of course these first attempts were purely imitative. The composers tried to imitate natural sounds and movements in music. Gombert wrote a clever and humorous "Bird Cantata." Jannequin, in his "Cris de Paris," tried to paint the street life of the French capital, while his "Le Bataille" is a military picture in music. These remarkable descriptive pieces were written for four voices, unaccompanied, and in polyphonic style. After trying to tell some kind of a story in secular music they tried it in religious music. One of Willaert's motets, at any rate, tells the story of Susannah, and is plainly a forerunner of the oratorio. We have seen now how the first period of the Netherlands school brought contrapuntal technics to a high state of development, how the second period produced a genius and a desire for pure beauty, and how the third period introduced a broader, simpler, and more imposing style into church music and made definite attempts at expression. We now come to the fourth period, which was destined to bring ecclesiastical counterpoint to its perfection. This period also produced a master of splendid genius, whose works live yet and ought to live as long as there is a place in the Roman Church for pure and lofty music. This man was Roland Delattre, usually known by the Italian form of his name, Orlando Lasso, or di Lasso.

Lasso was born in Mons, between 1520 and 1530. He studied at home, at Milan, Naples, and Rome, and at an early age became chapel master of the Church of St. John Lateran. In 1557 he went to Munich as director of the ducal choir. There he passed most of the remainder of his life, dying there on June 14, 1594. He was a contemporary of the great Palestrina, whose fame his far outshone. Lasso was celebrated all over Europe, was employed and honored by monarchs, and was called the "Prince of Music." He was one of the most prolific composers that ever lived. He is said to have written 2,500 works. Many of his compositions are in print today, and his quaintly beautiful madrigal, "Matona, mia cara," is often heard in concert. Other composers of this period were Jan Peters Swelinck, pupil of Cyprian di Rore, born at Deventer, 1540, died at Amsterdam, 1621, and Philip de Monte (1521-). Their work was by no means without merit, but it was overshadowed by that of their great contemporary.

Lasso was a complete master of the counterpoint of his time, but he aimed at making it a vehicle of expression for religious feeling, and succeeded. He adapted his style to his purposes. Sometimes he wrote pure hymn-tunes in four-part chords, much like our modern hymns. If he was writing for grand and imposing effects, he could handle the most complicated polyphony with ease. He wrote works for two and three choirs, and other works for only two voices. His famous "Penitential Psalms" are for two voices, and are marvellously beautiful and pathetic. Yet some of Lasso's music is as old-fashioned and stiff as Okeghem's. Again he becomes almost modern in his employment of chromatics. But there is one notable feature of Lasso's work: it contains no parade of contrapuntal difficulties for their own sake. On the contrary, it is admirable for the skill with which it conceals its own mechanical ingenuity and presents an appearance of spontaneity and fluency. It abounds in the highest and purest expression of religious feeling, and it is always beautiful as music per se. In fine we always know, when listening to the works of Lasso, that we are in the presence of a genius.

We have now reached the period at which Italy became the home of modern music. Willaert and Di Rore in Venice, Goudimel and Lasso in Rome sowed seed which was to produce beautiful fruit. At the same time influences were at work which introduced a simpler style into music and which made it an art more popular with the masses. One of these influences was the music of those very masses. The popular songs of the day had, as we have seen, long ago forced themselves upon the attention of the artistic composers. The time was now approaching when those composers turned to the popular music for suggestions as to the future development of their art. Before entering upon an account of the birth of a new style in music, the reader must go back with me and take a rapid view of the growth of the folk-song.

Progress of Popular Music

Troubadours, jongleurs, minnesingers, and meistersingers—Wagner's "Tannhäuser" and "Die Meistersinger" as historical pictures—The German volkslied—The musical guilds—The waits and the minstrels.

WE saw that as far back as Dufay's time composers began to introduce secular melodies into the mass. This was an evidence that the ecclesiastical composers had been forced to make attempts to popularize their works by a rude adoption of the melodies of the people. The question, therefore, naturally arises: Who were the composers of the secular music? Of course that is a question that cannot be answered very definitely, but we do know who were the secular musicians of the time, and we know that they were nearer the fundamental principles of modern music than the churchmen were. The enormous mass of ecclesiastical music produced in the middle ages was fit only for the worship of cathedrals. It could never have been made to utter the notes of human passion, and until some other style was found, the modern symphony, song, and opera must have remained impossible. Church counterpoint survives today only in church music and in the German fugue, a form of music which is conspicuous for its intellectual rather than its emotional qualities. The early secular musicians had no science at all, and very little art. Their music was, therefore, simple and unpretentious, but it contained the germs of our modern art forms, and it was bound in time to force its way into the studies of the fathers.

The secular musicians of the early time were wanderers on the face of Europe. They were the troubadours, jongleurs, minnesingers, meistersingers, and minstrels.

The whole race of strolling musicians in the middle ages almost certainly descended from the Roman comedians who were driven out of the seven-hilled city when Alaric swept down upon it with fire and the sword. They wandered into foreign lands to sing and pipe before the Frankish chiefs, now their lords and masters. In the earliest days they were simple vagabonds, whom the law did not allow redress for bodily injury wantonly inflicted. In the latter half of the twelfth and the early part of the thirteenth centuries these strolling musicians began to be employed in the mysteries and miracle plays, and thus gradually arose in the public estimation. Even before that time they had begun to be taken into the service of the knightly troubadours and minnesingers as accompanists, their French title being jongleurs.

Subsequently it became their business to go about singing the songs of their masters, in short, to become their publishers. The troubadours themselves were nobles, originally those of southeastern France. They got their first inspiration from the folk songs, but their own songs were distinguished by refinement and improved melody. These knightly singers existed simultaneously with the jongleurs, who sang and played for money. The most celebrated troubadours were King Thibaut, of Navarre (1201-1253), and Adam de la Halle (1240-1286). It is a notable and significant fact that the songs of the troubadours, like most of the folk songs, ignored the church modes and moved in the modern major and minor keys.

The last of the German minnesingers, Heinrich von Meissen, died in 1318, but the celebrated Confrèrie de St. Julien des Ménestriers, of Paris, lasted at any rate till 1741, for it is recorded that in that year Louis XV. made Jean Pierre Guignon "le Roy des Violons." The songs of the troubadours and wandering minstrels were the popular songs of the day of Columbus, and in Spain the troubadours still survived. The character of the music sung by these persons is well described by Fanny Raymond Ritter in her "Essay on the Troubadours." She says:—

"The merit of the troubadours in furthering the progress of music as an art was that they liberated melody from the fetters of calculation, gave it the stamp of individuality, and bore it on the wings of fancy into the domains of sentiment. They had the further merit of introducing new and peculiar changes of time, which, apparently irregular, were really forcible, symmetrical, and original. It is also more than probable that the troubadours received new ideas in regard to melody from the East; as they found among the Arabs not only a different system of tones, but many fanciful vocal ornaments then unknown in Europe, and which they introduced in their own songs on their return from the Crusades. But as harmony was in that day yet undeveloped, the flowing vine of melody received little support from it, and therefore often appears weak. The rules of composition were then highly complicated and ill classified, yet they were well understood by the best educated troubadours; and though their earlier songs were stiff, closely resembling the Gregorian chant in form and style, in some of the latter ones we find graceful melodies that leave little to be desired, and that possess more real variety and individuality of character than do the words attached to them."

It is not a far cry from France to Germany across the Rhine, and the chanson of the troubadour soon found its counterpart in the minnesong of the fatherland. The era of the minnesinger has been divided into three periods. The first, whose beginning is not definitely fixed, ended near the close of the twelfth century. The second period comprised the last decade of the twelfth century and the first half of the thirteenth. It was the golden age of the minnesong, the age of Wagner's "Tannhäuser" and the great Sängerkrieg at the Wartburg Castle, the age of the Landgrave Hermann, Wolfram von Eschenbach, and Walther von der Vogelweide. This time has been made alive for us by the genius of Wagner, whose contest in "Tannhäuser" introduces the actual personages of the real story. The third period was that of decline. The fourteenth century saw the gradual decrease of feudal power, and the burghers and artisans dared to do what had hitherto been reserved for their lordly masters. Thus the minnesong was supplanted by the meistersong, and the meistersinger became the musical lawgiver of Germany.

The songs of the meistersingers were somewhat stiff and formal, yet not lacking in melody, as that used by Wagner as the theme of his march goes to show. Perhaps no better description of a meistersong could be given here than that sung by "Kothner" in expounding the "Leges Tabulaturæ" to "Walther von Stolzing":—

Each mastersinger-created stave
Its regular measurement must have,
By sundry regulations stated
And never violated.
What we call a section is two stanzas;
For each the self-same melody answers:
A stanza several lines doth blend,
And each line with a rhyme must end.
Then come we to the "After Song,"
Which must be also some lines long,
And have its especial melody,
Which from the other diff'rent must be.
So staves and sections of such measure
A mastersong may have at pleasure.
He who a new song can outpour
Which in four syllables—not more—
Another strain doth plagiarize,
He may obtain the master prize.

In Germany, too, flourished the folk song. Who wrote the old volkslieder no one knows, but many of them have been preserved to us. The "Limburg Chronicle" contains a number in use between 1347 and 1380, and the "Locheimer Liederbuch" is a collection dated 1452. H. de Zeelandia, in his "Lehrcompendium," gives many in vogue in the first half of the fifteenth century. The essential features of the volkslieder are clearness and symmetry of melody and firmness of rhythm. The early ones also display a constant tendency to escape from the fetters of the ecclesiastical modes. In fact to them is due the final development of modern tonality.

The German church music of the time, from which developed the chorale, was founded on the volkslied. The familiar example of "Isbruck, ich muss dich lassen," set in four parts by Heinrich Isaak in 1475, and adapted after the Reformation by Dr. Hesse as "O Welt, ich muss dich lassen," was but the continuation of the practice of Heinrich von Laufenberg, who in the fifteenth century set sacred words to secular tunes continually. This brief review of the state of music in Germany in the time of the Netherlands school shows us that the volkslied and the meistersong were the ruling powers, and that there was as yet no foreshadowing of the mighty art which has since developed in the land of the Teutons.

In these days existed also the musical guilds which were the forerunners of the continental town orchestras. As far back as the thirteenth century the strolling musicians began to gather in towns, and there they formed societies for the protection of their common interests. Some of them became town pipers, and in the fifteenth century some were made town and corporation trumpeters. One result of the work of the guilds at this time was that musicians began to acquire some of the rights of citizenship. The guilds were accustomed to place themselves under the patronage of some noble, who selected from the guild a "piper king." It was his business to see that "no player, whether he be piper, drummer, fiddler, trumpeter, or performer on any instrument, be allowed to accept engagements of any kind, whether in towns, villages, or hamlets, unless he had previously enrolled himself a member of the guild." At irregular intervals a court was assembled, consisting of a mayor, four masters, twelve ordinary members, and a beadle, whose business it was to mete out punishment to guild offenders. These guilds were simply the musical protective unions of the day. Outside of the German nations, where these guilds did not exist, the ordinary musician was a stroller, with hardly any legal rights and no consideration. His occupation was regarded as menial, and the servants of the knights treated him with contempt. The jongleur who played the accompaniments for the troubadour, or even sang his songs when the master had no voice, was regarded as a servant and nothing more. The idea of any musician being entitled to the consideration of an artist, except the great church composers, would have been scouted.

In England the strolling musician was represented by the minstrel and the waits, and his status was about the same as it was on the Continent. In a somewhat better case were those who were under the protection of some prince or noble. For instance, the children of the chapel ate in the chapel hall with the yeomen of the vestry and were well cared for. They were the young students of choir singing, instructed by a master of song, who was appointed by the dean of the chapel. These children we find as a part of the household establishment of Edward IV., who died in 1483.

The musicians of the Church were in much better circumstances. As far back as the time of William the Conqueror we find that Hereford Cathedral had endowments which included support for seven choristers. We find similar endowments granted to St. Gregory's in 1363; to Wells in 1347; to the collegiate churches of Southwell, in Nottinghamshire; to Beverley, in Yorkshire, and Westminster. At Oxford, New College had an endowment for sixteen choristers, and Magdalen, All Souls', and St. John's had similar funds. Nearer to Okeghem's day the famous Dick Whittington, Lord Mayor of London, in 1424 founded an endowment for choristers in the Church of St. Michael Royal, which he built. Nevertheless, the first recorded case of a salaried organist is that of Leonard Fitz Simon, organist of Trinity College, Oxford, about 1580, at 20s. per year.

Here are two examples of the popular music of the early times,—the first a song by King Thibaut of Navarre, and the second the first part of the old meistersong used by Wagner in "Die Meistersinger":—

The reader will note that in the first of these there is a clearly marked rhythmic movement of the simplest kind. The tune is distinctly in the modern key of G major, and it is not polyphonic. The second tune is in F major and while its rhythm is not clearly indicated, it is plainly not a polyphonic composition. The directness of this kind of music and its suitability to the expression of simple feelings were bound to make themselves felt sooner or later in music. We are now to examine into the causes which led to the simplification of church music and forced composers to turn their attention more and more to the music of the people.


Chapter VI

The Simplification of Music

Causes which led composers toward a less complex style—The Renaissance and the Reformation—The Council of Trent—Palestrina and his music—Last days of the Roman and Venetian schools—The English cathedral composers—Characteristics of the period.

IT is hardly necessary to tell the reader that the methods employed in writing church music prior to the dawn of the seventeenth century were not always judicious. The use of secular tunes together with their texts prevailed for more than two centuries, and led to great laxity in the treatment of the liturgy. In the course of time too many composers came to regard the words of the mass as mere pegs to hang tunes on, and the tremendous complexity of the huge polyphonic works was such that the words could not be distinguished. One part would be singing "gloria in excelsis" while another was thundering "et in terra pax," and there was such a jumble of words and music that, while it was all very imposing, it was not comprehensible to the congregation. As long as the congregation knew very little Latin, and less music, this condition did not have serious effects; but the time had now come when the people began to ask questions. It becomes our duty, then, to inquire what influences led to reforms in church music. I shall first enumerate the influences and afterward discuss them in detail.

1. The revival of Greek learning in Italy after a lapse of seven hundred years.
2. The invention of printing.
3. The Renaissance.
4. Popular music.
5. The diffusion of musical learning among the people.
6. The Lutheran choral hymn and congregational singing.

In 1453 the Turks, under Mohammed II., slew Constantine, last of the Roman emperors, and overthrew Rome's eastern empire, whose capital was Constantinople. The Christian scholars of Turkey fled toward the home capital of their fallen empire, and took up their residence in Italy. These scholars were all masters of the Greek tongue, and they awakened a new interest in it and its literature. The field had been untouched for about seven centuries, and the whole treasury of Greek history, oratory, and poetry was reopened to the Italian mind. Its effects were wide and general. One of them was to lead to the study of the New Testament in the original tongue, and this study very speedily demonstrated the unworthiness of the Latin Vulgate used by the Church. Any blow at Latin was a blow at the authority of Rome. The whole Italian system of worship had been built upon the Vulgate, which was in the language authorized in the Roman Church throughout western Europe, and used as the sole means of intercommunication between its branches in various nations. Doctrines and edicts alike proceeded from Rome in the ancient language of the city, and to throw discredit upon the veracity of that tongue in the Vulgate was to subject it to general doubt and suspicion. Such doubt did certainly spread among the people, who began to demand a clearer comprehension of the liturgy. To this end they desired a less complex setting of the musical part of the church service.

This demand was powerfully backed by the introduction of printing in 1444. This introduction resulted in lowering the price of books, and a plentiful supply of cheap reading attracted readers. Hence the mass of the Roman Catholic laity became readers as well as listeners. The whole system of worship had been based on the existence of a non-reading public. But now the age of popular inquiry began, and it became necessary for church music to abandon its complexity and address itself to meet the demands of awakening intelligence.

The dawn of the Renaissance in art was caused by the revival of Greek learning, which reintroduced Greek models. The enormous effect of a new contemplation by the Italian mind of Doric architecture and Greek sculpture can hardly be comprehended by us to whom these things are so familiar. The force and beauty of simplicity were brought home to the people by the very examples which awoke in them a desire for imaginative life and personal expression. The Renaissance led to a clearer, stronger, more eloquent style in all art, and in time it was bound to make itself felt in music. The fact that Leonardo da Vinci worked before Josquin des Prés proves nothing except that music was behind the other arts in the development of her technic, and had to work out her own laws of existence before she could feel the influence of reformatory thought.

The popular music of the time naturally appealed to composers as their feeling for distinctly outlined form increased, and this feeling was directly influenced by the artistic teachings of the Renaissance. As art remodelled itself on Greek patterns, and architecture found in the Doric lines a relief to the endless details of the Gothic, so music inclined toward the simple contours of the song-forms. The elementary attraction of pure rhythm grew in potency as composers realized more clearly that it was one of the fundamental components of music; and with a recognition of this fact came that of the deeper significance of chord harmony. The folk-song itself had always clung to the major and minor scales, and had not often employed the purely ecclesiastical modes. The mode known as the Ionic—the old Greek Lydian mode, condemned by the ancients as lascivious—was nothing more nor less than our major scale of G, and as such the church composers knew it. Its possibilities made themselves more and more clear as the artistic musicians of the day studied the popular tunes, and so in time it came to its true seat of honor in music.

A knowledge of music had begun to spread among the people. Not only did the constant hearing of the noble masterpieces of their time tend to cultivate their taste, but they began to practise music themselves. Conservatories had been founded in Venice, Rome, and other cities, and as far back as Willaert's day it was fashionable for young ladies of good family to learn to play the monochord, one of the precursors of the piano. The music written for the instrument was precisely like that for the organ, polyphonic in style and learned in treatment. The study of such music was naturally very difficult for beginners, and it became necessary to supply them with something simpler.

The music of the Roman Church was brought into strong contrast with that employed by Luther in his work of the Reformation. Luther insisted on the exercise of individuality in worship. He held, contrary to the Church, that every man had a right to study the Bible for himself. He even gave communion to the laity. In direct line with such work was his revival of congregational singing, which had been generally unpractised since the days of Ambrose. The first Lutheran hymn-book was published in 1524. Luther employed many extant folk songs and caused new tunes like them to be written. He is said to have written "A stronghold sure." These Lutheran hymns were broad and simple chorals, like those of the Protestant Church of today. The spread of their use among the Protestant congregations of the time was an attraction toward that form of worship which the authorities of the Roman Church could not ignore, and hence the Catholic composers moved toward a simpler style.

The story of what followed the recognition of these influences by the fathers of the Church has been very prettily told, but unfortunately it has been of late discredited. The story is that two parties arose in the Church, one of them demanding the abolition of all the extant church music and a return to the plain chant of Gregory, and the other that the music of the time be preserved, but its style simplified. The Council of Trent (1562) discussed the matter, and in 1563 Pope Pius IX. appointed a commission of eight cardinals to take measures of reform. Cardinals Borromeo and Vitellozzi, appointed as a sub-committee, went to Palestrina, whose music had already attracted attention, and asked him to write a mass demonstrating that the church music of the time could be preserved. He entered upon his task with such enthusiasm that he wrote three masses, of which that called the Marcellus mass was performed with enormous success.

This story has been proved to be a myth. The Council of Trent did pass a resolution that a complete reform of church music was necessary, but the demand was based, not on the character of the music, but on the fact that it made the text of the liturgy unintelligible. The Council furthermore issued a mandate to bishops to banish improper music from their churches. This was, of course, aimed at the secular airs, or those which resembled them. The mass of Marcellus was not written to order, and there was nothing new in its style. The mass is simply a model of all that was best in Palestrina's day. It embodied all that was noblest in the polyphonic style developed by the Netherlands school. Its melody is pure, sweet, and fluent, and its expressive capacity perfectly adapted to the devotional spirit of the text. Palestrina's contemporaries, such as Lasso, and some of his predecessors, wrote in the same style. Lasso's "Penitential Psalms" are much simpler in style than this mass. Its apparent simplicity lies in the fact that its profound mastery of technical resources conceals its superb art. The polyphonic writing is matchless in its evenness; every part is as good as every other part. The harmonies are beautiful, yet there is apparently no direct attempt to produce them. They seem just to happen. But above all other qualities stands the innate power of expression in this music. It is, as Ambros has hinted, as if the composer had brought the angelic host to earth.

With Palestrina church polyphony reached its highest and its final development. The search after simplicity led composers in a path diverging widely from the old contrapuntal highway. New developments in secular music were soon to come about, and still more powerfully to influence church composition. The harvest and the glory of vocal counterpoint had come, and thenceforth musical art was to develop along new and hitherto unexpected lines. A few words should be written here concerning the career of so great a man as Palestrina, who has been universally accorded a seat among the Titans of music. His full name was Giovanni Pierluigi Sante, and he was called Palestrina from the place of his nativity. The date of his birth is uncertain, but it was probably 1514. The portrait of him in the pontifical chapel at Rome has an inscription to the effect that he died in 1594, aged eighty. He was the son of poor peasants and got his first musical instruction as a choir singer. In 1540 he went to Rome and became a student in Claude Goudimel's conservatory. At the age of thirty he published his first compositions, and some of them are still heard in the Sistine Chapel occasionally. [6.1] He had previously served a short period as organist and choir master in his native town, and in 1548 he married. In 1551 he succeeded Arcadelt as choir master of St. Peter's, Rome, and the Pope made him one of the singers of the Papal Chapel. In 1571 he was made chapel master of St. Peter's, and later, in conjunction with his younger contemporary Nanini, he founded a music school in Rome. The influence of this school was very great, and it kept the "Palestrina style" alive in Europe for nearly a century. Palestrina died on Feb. 2, 1594, and the Supreme Council of the Church had his body laid in the basilica of the Vatican with the honors usually shown to a cardinal.

[6.1] At the time of writing (October, 1897) Palestrina's works are not performed as often as they used to be in the Papal Chapel, and there is a determined movement on the part of some of the clergy for their restoration and a more frequent use of the Gregorian chant. The movement is a healthful one, and I wish it success.

Before leaving the subject of Palestrina, let me endeavor to make clear to the reader wherein his style is so fine. Composers before him had begun to aim at the simplification of church music. They sought to accomplish their purpose by breaking the shackles of canonic law. The canon had demanded the most exact imitation in the different voice parts. The new style allowed the greatest freedom. The result was that free polyphony took the place of rigid canon. Consequently, composers were able to devote more attention to the development of fluent, beautiful, and expressive melody. The merit of Palestrina's work was that it carried this style to perfection. His compositions became the models for succeeding composers, and indeed they remain to this day unequalled as examples of pure church music. In Palestrina's music one must note the absence of rhythmic effects, of modern tonality, and of the note of passion. Palestrina paid little attention to folk-music, but sought to attain simplicity of style by preserving the old church scales, avoiding chromatic harmonies, and by generally preserving purity and contemplative feeling. His writing is marvellous in its contrapuntal skill, which makes the apparently independent melodies of the different voice parts constantly combine in simple and lovely chords. The lack of contrast in his music has often been quoted as a fault; but it was in accordance with Palestrina's own theory that church music should always be dignified, and should never contain anything exciting.

As we have now reached the period at which artistic music began to develop in all its branches, it will be most convenient to narrate the progress of Roman Catholic church music subsequent to Palestrina's time before passing to other topics. The reader must bear in mind that this music was still designed to be sung without accompaniment, in order that the tone-quality of pure vocal sound might be untainted. When the organ was first used it simply doubled the voice parts, and when independent accompaniments began to be written they considerably altered the character of church music. There were now two distinct schools of Catholic composition,—that of Rome, and that of Venice. The former followed the pure diatonic style of Palestrina; the latter was influenced by the style of Willaert and the chromatic music of Di Rore. The chief masters of the Roman school were Nanini, Vittoria, Anerio, and Allegri. Giovanni Maria Nanini was born in 1540 and died in 1607. He was a coworker with Palestrina, and was the teacher of many of the succeeding composers. His "Hodie nobis cœlorum Rex" is still sung at Christmas in the Papal Chapel. Tommaso Ludovico da Vittoria was born about 1540, and died about 1604. He is regarded as one of the greatest of Palestrina's successors. A goodly number of his works has been preserved. His Requiem, written for the funeral of the Empress Maria (1603), is conceded to be his greatest production, and is one of the most notable compositions of that period. "Technically considered, it is a marvellous blending of old independent movement of parts with modern dissonances and progressions. Spiritually considered, it is a wonderful expression of poignant personal sorrow, chastened by religious contemplation and devotion." The marks of change here are the use of the dissonance and the expression of personal feeling. The dissonance in music embraces all those harmonies which sound harsh to persons accustomed only to elementary chords like the tonic, dominant, and subdominant. They are used most freely in modern operatic music, especially that of Wagner, and have always been employed to express passion of some kind. Palestrina avoided them. Felice Anerio (1560-1630) wrote many admirable masses. Gregorio Allegri (1586-1652) is best known as the composer of very fine "Misere" now sung in Holy Week in the Sistine Chapel. This work is regarded as equal to some of Palestrina's.

The Venetian school, after its earliest period produced two great composers from one family. These were Andrea Gabrieli (1510-1586) and his nephew Giovanni Gabrieli (1557-1613). The former followed Willaert's plan of writing for antiphonal choruses, but he employed most frequently three instead of two. The latter was more of an instrumental composer than his uncle, and hence conceived the idea of writing instrumental accompaniments. In his "Surrexit Christus" he used an orchestral accompaniment of first and second violins, two cornets, and four trombones. This work of Giovanni Gabrieli's fairly marks the termination of the era of a capella (unaccompanied) polyphonic church music. The opera had been born, and so had the oratorio, and church music began to borrow ideas from them. Giovanni Legrenzi (1625-1690) increased Gabrieli's orchestra to nineteen violins, two violas, three viole da gamba, four theorboes (lutes of large size), two cornets, one bassoon, and three trombones. Antonio Lotti (1667-1740) was an opera writer as well as a church composer, and he wrote masses full of passionate feeling. His later works are full of passages in which the voices alternate with the instruments and there are accompanied solos and choruses. With Lotti, who used unaccompanied choruses occasionally, we bid a final farewell to the great period of a capella church music, and enter upon the era in which music for the church was made in the same way as other kinds. The masses of Mozart, Beethoven, Cherubini, and other modern writers are all richly instrumented.

England had fairly kept pace with the Continent in her mastery of polyphony, which so early produced the remarkable canon "Sumer is icumen in." Thomas Tallys (born about 1520, died Nov. 23, 1585) was one of the greatest of the English masters, and is regarded as the father of English cathedral music. His works do not equal those of his contemporaries in inspiration,—he was neither a Lasso nor a Palestrina,—but he had a large command of polyphonic technic. One of his notable works was a motet, entitled "Spem in alium non habui," written for eight choirs of five voices each, in antiphonal style. His best known work, however, is a Litany and Responses. His pupil, William Byrd (born about 1538, died July 4, 1623), wrote many admirable church works notable for the majesty of their style. Orlando Gibbons (died 1625, at the end of the Netherlands period) was the last great light of the English school.

During the whole period of church counterpoint, which never lost the radical elements of its character until after Legrenzi's day, music felt the influence of the old chant and the early study of the canonic style. In concluding the account of this period, I cannot do better than to quote a few luminous sentences from the admirable "Evolution of the Art of Music" by Dr. C. H. H. Parry: "Of definite principles of design beyond this elementary device [the canon] these composers had but few. Their treatment of musical figures and melodic material is singularly vague. The familiar modern practice of using a definite subject [part of a distinct tune] throughout a considerable portion of a movement, or at certain definite points which have a structural importance, was hardly employed at all. The voices, which entered one after another, naturally commenced singing the same words to phrases of melody which resembled each other. But composers' ideas of identity of subject matter were singularly elastic, and even if the first half-dozen notes presented similar contours in each voice part successively, the melodic forms soon melted into something else, and from that point the movement wandered on its devious way without further reference to its initial phrases." This points to one of the fundamental differences between the music of the polyphonic era and that of the monophonic, in which one voice or instrumental part (as the treble of a piano) uttered a melody full of periodical repetitions of the germinal tune-thought, and the other parts supplied an accompaniment of chords. This style of composition was developed first in the opera and afterward by instruments. It will be more convenient to take up the progress of instrumental music first, and at the outset let us review the evolution of the piano.


Chapter VII

The Evolution of the Piano

Plucking and striking strings—The dulcimer—Invention of the keyboard—The clavichord and its action—Manner of playing the clavichord—The harpsichord family—Invention of hammer action—Claims of Cristofori—Modern improvements—Equal temperament.

THE piano, like all our contemporaneous musical instruments, is the result of a long development. Its fundamental principle is the setting of a stretched string in vibration by a blow, the vibrations acting upon the air so as to produce sound. A subsidiary principle (subsidiary because common to all stringed instruments, such as violins, harps, or guitars) is the shortening or lengthening of a string in order to obtain a higher or a lower note. In the piano, the application of this principle gives us a number of strings of different lengths. In the violin we have only four strings, but the length of the vibrating part is altered by pressing down the strings at different points with the fingers of the left hand. Before the idea of setting strings in vibration with a bow was conceived, they were plucked with the fingers, as in the case of the harp and the guitar, and it is probable that this is the oldest method of causing strings to sound. The Hebrew kinnor, the first musical instrument mentioned in the Bible (called "harp," Genesis iv. 21), was either a lyre or a small harp, and, according to Josephus, it was played with a plectrum, a small piece of ivory or steel, used to pluck the strings. Egyptian pictures of great antiquity show players using their fingers upon harp strings. At the same time the Egyptians were well acquainted with the principle of dividing a string by pressing upon it with the fingers of the left hand, as is proved by their pictures of lute players.

But the use of a blow to set a string in vibration was also known in very early times. The instrument called a dulcimer, which is always seen now in Hungarian orchestras, is almost as old as the harp. It consists of a number of strings stretched across a shallow box, which acts as a resonator, and set in vibration by two little hammers in the hands of the player. It was this instrument which suggested the hammer action, and it is this action which makes the fundamental difference between the piano and its immediate precursors. An instrument similar to the dulcimer was the citole, the chief difference being that the strings were plucked with the fingers. Add the principle of stopping the strings with the fingers of the left hand, and the citole becomes the zither. In Lydgate's "Reson and Sensualité (circa 1430) "cytolys" are enumerated among other instruments.

The first important step toward the evolution of the pianoforte was the invention of the keyboard. The origin of this important part of the instrument is uncertain. It is probable that it was first applied to the organ. At any rate, it is said that a keyboard of sixteen keys was attached to an organ built in the Cathedral of Magdeburg at the close of the eleventh century, while most historians date the clavichord or the clavicytherium two centuries later. It is possible, however, that some sort of rude arrangement of keys was employed in the monochord, an instrument used for measuring the scientific intervals between notes of different pitch. It is said to have been invented by Pythagoras in the sixth century before Christ. It consisted of an oblong box with one string stretched across it, and a movable bridge for dividing (or stopping) the string at different points. The continual shifting of the bridge was very troublesome, and as early as the second century (according to Claudius Ptolomæus and Aristides Quintilianus) there was a four-stringed instrument called a helicon. It is surmised that the famous teacher Guido d'Arezzo (born about 995) was the first to use the monochord in teaching singing, and that he devised some kind of a keyboard, because in one of his writings he advises his pupils "to practise the hand in the use of the monochord."

The keyboard having been invented, whether for monochord or organ, its application to stringed instruments of the dulcimer or citole family naturally followed. It is impossible to tell whether the first action was a plucking or a striking one, for there are no records, and it is easily conceivable that both may have been used simultaneously in different places. Guido's action is supposed to have consisted of a straight lever with a bridge on the inner end. When the outer end, the key, was struck the bridge arose, gave the string a blow which set it in vibration, and remaining pressed against the string, divided it and determined its pitch. This subsequently became the action of the German clavichord. Another action consisted of a similar straight lever with a piece of quill protruding from the inner end. When the outer end was pressed down the inner end moved past the string and the quill plucked it, causing it to vibrate. This became the action of the clavicytherium, which some writers, without good ground, say was antecedent to the clavichord, and subsequently of the Italian spinet, the harpsichord, and the virginal.

The first mention of the clavichord and harpsichord is found in the "Rules of the Minnesingers," by Eberhard Cersne, A. D. 1404. The celebrated musical theorist, Jean de Muris, of the University of Paris, writing in 1323, and enumerating musical instruments, mentions the four-stringed monochord, but says nothing of the clavichord or harpsichord. This gives reasonable ground for the inference that those instruments were either not invented at that time or had so recently appeared that they were not yet known in Paris, then the centre of musical culture. We are quite safe in assuming that both instruments date from the thirteenth century, and as they were the immediate ancestors of the piano, we must give them especial attention. The famous collection of Mr. Morris Steinert, of New Haven, contains examples in good working order of all the different kinds of clavichords, harpsichords, spinets, and early pianos, and it has been my privilege to examine and play upon all these instruments, thus obtaining a singularly effective object lesson in the history of the piano. The clavichord was always built in oblong shape, like our square piano. The keyboard was precisely like that now used, except that some builders made the naturals black and the sharps and flats white. The principle of the action remained that of the old monochord. The key was pivoted just inside of the front board of the case, and consisted of a single straight shaft of wood. On the inner end was a thin, slablike upright of brass, called a "tangent." When the player struck the outer end of the key, the tangent was driven upward against the string, causing it to vibrate. The tangent also acted as a bridge, and divided the string into two unequal parts, the longer of which gave out the tone. The shorter section was prevented from sounding by a narrow band of cloth interlaced with the strings at that end of the instrument. This band also acted as a damper, and caused the whole string to cease vibrating the moment the tangent was lowered. Clavichords made before 1725 (or about that year) had fewer strings than keys. One string had to produce two and sometimes three tones. This was accomplished by the use of the tangents, which divided the string at different lengths, as the violinist does with the fingers of his left hand. These instruments were known as "gebunden," or bound.

About 1725 Daniel Faber of Crailsheim made instruments with one string for each tone, and such clavichords were called "bundfrei" (bound free) or "ungebunden" (unbound). In the latest clavichords each note had two strings tuned in unison,—a contrivance which gained power at the expense of some of the lovely expressiveness of the instrument.

The reader will understand that, as the clavichord string ceased sounding as soon as the tangent was permitted to drop by lifting the finger from the key, the method of playing it was different from that employed for the piano. A hard blow was of no use; it only twanged the string disagreeably. Pressure, with its direct communication of the finger-touch to the string, was the secret of clavichord playing, and it was this which made the instrument so beautifully responsive to the thought of the performer. By forcing the pressure a little a sort of portamento effect could be obtained, and by causing the finger to shake up and down on the pressed key one could get a faint and pathetic tremolo from the vibrating string. This effect the Germans called "bebung," and it was one of the most familiar graces of clavichord playing. No one who has played upon a clavichord can fail to see how thoroughly the instrument works its way into the confidence and love of an artist, and there is no room for wonder that it was the intimate friend of the great Bach.

It is difficult to arrive at satisfactory conclusions from the statements of early writers in regard to instruments of the harpsichord family. Scaliger, born in 1484, says that Simius, who lived in the last period of Greek music, invented the Simicon. In this the tone was produced by tangents, which were subsequently armed with crow quills to pluck the strings. Adriano Banchieri, in his "Conclusioni nel suono dell' organo" (Boulogne, 1608), said that the spinet, one form of harpsichord, was invented by Giovanni Spinetti, and took its name from him. Banchieri had seen such an instrument with the inscription, "Joannes Spinetus Venetus fecit, A. D. 1503." But the fact that De Muris enumerated the instruments of his time without naming the harpsichord or any of its kindred, while Cersne distinctly mentioned it in 1404, shows that it was certainly much older than either Spinetti or Scaliger. Ottomarus Luscinius, a Benedictine monk, in his "Musurgia" (Strasburg, 1536), describes the virginal, a square instrument, of which the strings were plucked by plectra. Marin Mersenne, born at Oise, in 1588, in his "De Instrumentis Harmonicis," describes the clavicymbalum, which, according to his figure, is the same instrument as the spinet of Banchieri and the virginal of Luscinius.

There were, indeed, several varieties of shapes and many names for what were essentially the same instrument. Some were square, some were trapezoid, like our grand piano, and some were upright, but they all had the same plectral action and produced the same kind of tone. It will be readily understood that these instruments were incapable of gradations of power. No matter how forcibly or how gently the key was pressed, the elasticity of the plucking quill remained constant, and so produced just the same amount of twang from the string. Wooden uprights, called jacks, were placed at the inner ends of the key levers, where the tangents were in clavichords, and the quills ran through them. In some instruments pieces of hard leather were used instead of quills. Bach was acquainted with the harpsichord, though he always preferred the clavichord. Handel, Scarlatti, and Mozart were all great harpsichord performers. The instrument held its favor among musicians for a considerable time after the introduction of the piano, to which it finally had to yield the supremacy.

The first famous harpsichord builder was Johannes Baffo, Venice, 1574, but the most celebrated makers were: Hans Ruckers, Antwerp, 1575; Andreas Ruckers, his son, 1614, Tschudi and Kirkman, the English builders of Handel's day. Kirkman built harpsichords with two banks of keys and several sets of strings, which were controlled by stops similar to those of an organ. This was an attempt to overcome the dynamic monotony of the instrument, but I can testify from careful trial of the fine Kirkman harpsichords in the Steinert collection that the attempt was not a brilliant success. You can get an approximate idea of the sound of a harpsichord by plucking the strings of a modern piano with the plectrum of a mandolin, or with a common quill toothpick.

The invention which overthrew the clavichord and the harpsichord and brought into existence the piano was the hammer action. For years the problem of applying the keyboard to the principle of the dulcimer, already explained, had occupied the minds of instrument builders. The solution was the work of Bartolomeo Cristofori, born at Padua, May 4, 1653, and it was made public in 1711. Two others claimed the honor: Gottfried Silbermann and Christopher G. Schröter. In 1726 Silbermann made two pianos and showed them to Bach, who condemned them because of their heavy touch and the weakness of their trebles. Silbermann was discouraged, but according to Agricola, a contemporary writer, he worked at improvements upon his instruments, and sold one of them to Frederick the Great, in whose music room it stood till 1880. It was then examined by Bechstein, the leading German piano maker of today, who found that it contained the Cristofori action. The priority of Cristofori's claims is established by an article written by Scipione Maffei and printed in the "Giornale dei Litterati d'Italia," in 1711, with a diagram of the inventor's hammer action. A translation of Maffei's article will be found in Rimbault's "The Pianoforte." (London, 1860.) It was also published in German in Matheson's "Musikalische Kritik," in Hamburg, 1725, so that the contemporaries of Silbermann and Schröter ought to have known of Cristofori's work. Indeed, Schröter's claim was made by himself in a letter written in 1738, which appears to have been evoked by irritation at Cristofori's glory.

It should be noted here that in the letters of an instrument maker named Paliarino, written in 1598, the instrument "piano e forte" is twice mentioned. It has been conjectured, and probably rightly, that this was a harpsichord with contrivances for loud and soft effects, for it is unlikely that even a rude hammer action could have been in existence more than a century before Cristofori's invention. It is, however, probable that some attempts were made before his, for his was altogether too satisfactory to have been anything but the result of a development. Nevertheless it was the first hammer action of permanent value, and its essential principles are employed in the finest actions of today. Therefore Cristofori fairly deserves the honor of inventing the piano. The instrument, however, did not gain great favor in Italy, owing to the inability of the harpsichord players to acquire the right touch, and it soon fell into disuse. Silbermann, however, following the details of Maffei's letter before-mentioned, built pianos, and other German makers, notably Friederici of Gera, who is said to have made the first square piano, followed his lead. At least as early as 1766 Johannes Zumpe built square pianos in England.

It would fill a volume to narrate the history of the successive steps in the development of the piano since the days of Zumpe. It is possible, however, to point out a few of the important steps. The famous maker, John Andrew Stein, Augsburg, was a pupil of Silbermann, and was born in 1728. He left a son, Andrew, also a maker, and a daughter, Nanette, who became Mrs. Streicher, and was the head of a great piano house in Vienna. The elder Stein's pianos were admired by Mozart, while Nanette Streicher's pianos were used by Beethoven. Before the time of the elder Stein the forte and piano effects, which gave the instrument its name, and which were then as now, produced by the action of the dampers, were obtained by operating "two iron springs, ornamented with copper knobs, in that part of the chest nearest the bass. In order to move these springs it was necessary that the player should use his left hand, and consequently he was obliged for a moment to quit the keyboard. Stein improved these springs by making them act by means of knobs placed against the knees." The modern pedals are first found in John Broadwood's patent of 1783. The pedals have been much improved since that time, and have played a very conspicuous part in the development of piano playing and of piano music. The "loud" pedal, as it is commonly called, is less used by pianists to gain force than to prolong sound, which before its invention could only be done by keeping the keys pressed down. With the dampers raised by the "loud" pedal, the strings struck continue to vibrate, while the fingers are free to go on striking other keys. This enables pianists to do far more than they could in early times in the way of producing sustained tones and modulations of harmony, and hence composers for the instrument are able to write passages which would formerly have been impossible.

Double, and even triple, stringing had been introduced in clavichords, and was continued in pianos. The elder Stein invented the shifting of the keyboard which causes the hammer to strike only one string instead of three. This contrivance is used by some of the best makers of the present day. Stein also improved the "escapement," the arrangement by which the hammer falls back the instant it has struck the string, and this, with other features of the action, was further developed by Streicher, so that the Viennese pianos became famous for the extreme lightness of their touch, and music written by composers in that part of the world was designed to meet this quality. The English pianos, meanwhile, were built with heavier strings and a deeper fall of the hammer, so that greater sonority was attainable, and composers wrote for them bold passages in successions of heavy chords, which would have gone for nothing on a Viennese piano. At the very outset Cristofori had to shift the pins to which the wires were attached, from the soundboard, which would not stand the strain, to a separate rail. It became necessary to brace the whole interior with steel arches, of whose inventor there is no record, but Broadwood was the first to introduce the method now employed. Sebastien Érard, a celebrated French maker, introduced many improvements in the action and devised what was called then the "celeste" pedal, by which the hammers struck a strip of leather interposed between them and the strings. The leather is now replaced by felt. The iron frame, now replaced by steel and found in all fine pianos, was invented by Alpheus Babcock of Boston in 1825. Frederick W. C. Bechstein, of Berlin, in 1855 combined iron frames and the powerful English action in his instruments, and took a commanding position. The upright piano was patented Feb. 12, 1800, by John Isaac Hawkins of Philadelphia. Subsequent developments in the piano have been of too wide a range to be mentioned in the space at my command, and at any rate have all been in the nature of improvements,—highly important, indeed, but without radical departure from the fundamental features of the instruments.

A few words, however, must be said on the subject of equal temperament. Previous to the time of Bach and Jean Philippe Rameau, the scale of the piano was arranged according to the laws of acoustics. It is impossible to enter into this fully, but the result was that a piano could not be tuned to play in all the twenty-four keys. This is difficult to explain, but I shall endeavor to make it clear. The pitch of a tone is determined by the number of vibrations it makes in a second, and it follows that there must be a regular ratio of increase in the number of vibrations of the notes of a scale as we proceed upward. This establishes the scientific basis of the scale. Now, any one who is at all acquainted with the piano knows that the same black key is struck to produce either C sharp or D flat. But this has been true only since Bach's day. Previous to that time instruments were timed according to the scientific laws, and by these we find that the C of the third octave has 256 vibrations, the C sharp 266.66, and the D flat 276.48. Thus D flat is a higher note than C sharp, and scientifically requires a differently tuned string and a separate key. The same trouble confronts us with most other notes, so that "theory requires no less than seventy-two keys to the octave in order that the musician may have complete command over all the keys employed in modern music."

In order to reduce the octave to twelve semitones with twelve keys and to make the sharps and flats agree, as they do now, the system of equal temperament deliberately puts out of tune every interval except the octave. By slightly lowering some and raising others, the present scale was obtained. Its advantage is that it makes it practicable to play in all twenty-four keys, and because of the identity of the sharps and flats it becomes easy to modulate from one key to another. For instance, C sharp, which is the distinguishing note of the scale of D major, is also D flat, and thus it becomes easy to modulate from D to D flat, which leads to G flat, a very remote key. This gives the modern composer immense freedom of style, and adds greatly to the key complexity of music, whereas, before the adoption of the system of equal temperament, composers had to confine themselves to a few closely related keys.

Who invented the system of equal temperament, no one knows. It is mentioned in the "Harmonic Universelle" of Marin Mersenne, the French writer before quoted, but it is quite certain that it was not extensively employed before the time of Bach, who brought the system to practical perfection, and demonstrated it in his "Well-Tempered Clavichord," a set of twenty-four preludes and fugues going through all the keys. The science of equal temperament was first set forth in a satisfactory manner by Jean Philippe Rameau, the French opera composer, in his "Traité de l'Harmonie," Paris, 1722.
