This dissertation explores the use of topics for dramatic purposes in Mozart's Così fan tutte. The five analytical chapters are organized around a central question: how do pastoral and fanfare topics shape the plot of Così fan tutte? Chapter 2 highlights the role topics and tropes play in emplacing and nuancing emergent meaning in the Così fan tutte motto. Chapter 3 examines transformative topical tropes in "Ah guarda, sorella." Chapter 4 shows how the horn fifths and fanfare topics in "Per pietà, ben mio" frame Fiordiligi's choice: the Albanian or Guglielmo. Chapter 5 illustrates the relationship between fanfare topics and galant recitative schemas to articulate formal boundaries between accompanied recitatives and arias. The expectations of closure emplaced by the examples from Così fan tutte nuance a reading of "Hai già vinta la causa!" from Le nozze di Figaro. Chapter 6 discusses the role of recitative intrusions and their articulation of the Count's unrest in "Vedrò mentre io sospiro." Detailed analyses and close readings of the topics and tropes in this dissertation drawn from throughout Così fan tutte showcase Mozart's rich deployment of topics in varied musical and dramatic roles.

Paul Schoenfeld (b. 1947) is considered one of the major American composers of the present day to have incorporated many different styles in his music. Although Schoenfeld primarily uses a combination of folk, popular music, klezmer, and jazz in most of his compositions, he has also incorporated other distinctive musical styles in his works, such as neo-Baroque, particularly in his Partita for Violin and Piano (2002). The purpose of this dissertation is to explore the eclectic combination of neo-Baroque and klezmer elements found in Schoenfeld's Partita. This research provides a detailed comparative analysis of his work with Johann Sebastian Bach's Clavier-Übung I, BWV 825–830, and 6 Sei Solo a Violino senza Basso accompagnato, BWV 1001–1006, primarily to see how Schoenfeld made use of Baroque forms, imitative passages, rhythms, and other stylistic features, then fused them with klezmer elements. Klezmer is a genre of music stemming from the Eastern European Jewish tradition; its distinctive characteristics are modal scales and Hasidic vocal ornaments. Knowing the mixture of Baroque and klezmer stylistic influences should help performers to interpret the piece.
