The Development of Certain Tendencies in Modern Opera / Thesis for the degree of Bachelor of Music

A historical and quantitative study traces the origin and evolution of structural tendencies in opera, focusing on form rather than harmonic analysis. It compares changes in number of acts, cast composition, orchestral proportions (overtures, ballets, ritornelli), solo writing and voice distribution, types of recitative, ensemble forms, and chorus usage. Thirty-four operas are measured by counts of measures assigned to each factor and summarized in seven tables covering characters, orchestration, solos, recitative, ensembles, and chorus. A narrative survey accompanies the data, charting developments from early precursors and Renaissance dramatics through Gluck, the Rossini school, Wagner, and post‑Wagnerian national trends, with an appendix and bibliography.
