Jean-Michel Defaye composed Á La Maniére de Debussy in 2001 as part of a series of trombone solos written to emulate the compositional styles of significant predecessors. This study compares Á La Maniére de Debussy to the harmonic, melodic, and rhythmic practices of Claude Debussy (1862–1918), an innovative French composer and recognized figure of musical Impressionism. At present, there is limited scholarship on Defaye’s Á La Maniére de Debussy and its compositionally imitative nature. The first section of this document presents a survey of historical information, current literature, and methods of examination. The second section provides biographical information on composers Jean-Michel Defaye and Claude Debussy. The third section exhibits a compositional comparison of Á La Maniére de Debussy to Debussy’s use of harmony, melody, and rhythm. The final section draws a conclusion to the piece’s importance to the trombone solo repertoire and includes an interview with French trombonist Jacques Mauger who collaborated with Defaye on Á La Maniére de Debussy. Although this document is not a performance guide, an informed performance of Á La Maniére de Debussy requires a trombonist to understand Debussy’s unique treatment of harmony, melody, and rhythm.

À la Manière de Stravinsky is one piece in a series of works composed by Jean-Michel Defaye that written emulating the compositional styles of significant composers of the past. This dissertation compares Defaye’s work to common compositional practices of Igor Stravinsky (1882 – 1971). There is currently limited study of Defaye’s set of À la Manière pieces and their imitative characteristics. The first section of this dissertation presents the significance of the project, current literature, and methods of examination. The next section provides critical information on Jean-Michel Defaye and Igor Stravinsky. The following three chapters contain a compositional comparison of À la Manière de Stravinsky to Stravinsky’s use of rhythm, articulation, and harmony. The final section draws a conclusion of the piece’s significance in the solo trombone repertoire. This study will add to the published material on Jean-Michel Defaye and this influential series of pieces and is intended to further the interest of research into the works of this important composer.

The purpose of this dissertation is to investigate and document the compositional components and innovations in the compositional style of Jean-Michel Defaye as they relate to two of his works for solo trombone, Deux Danses (1953, trombone and piano) and Fluctuations (1980, trombone solo, six trombones and two percussionists.) This document investigates the circumstances surrounding the creation of each piece as well as the compositional processes of Monsieur Defaye. Jean-Michel Defaye is an important composer for his commitment to the quality and challenge of the trombone literature he creates. The importance of Deux Danses is in the fact that it was this piece that put Defaye in the international spotlight. Solo works with chamber ensemble, such as Fluctuations, must be more seriously considered for performance if the standard solo repertoire for trombone is to be further expanded. Jazz style is an integral part of both of these important works and a necessary component to fully realize the composer's intent. Monsieur Defaye has demonstrated a commitment to composing for the instrument over the long term and has a sustained interest in participating in the further development of serious literature for all brass instruments. This study will add to the limited published material on Defaye and is intended to further the cause of research into the works of this important composer.
