An introductory essay outlines basic principles for appreciating music and sketches the historical development of musical resources. Subsequent chapters present concise studies of six composers—Grieg, Dvořák, Saint-Saëns, Franck, Tchaikovsky, and Brahms—blending biographical detail with analysis of style, technique, and expressive character. The author places each figure in the broader evolution of musical art, assessing relative influences and contributions. A closing essay considers the relationship between music and human experience, arguing that aesthetic judgment depends on both inherited technical means and the emotional life that gives music meaning.
