This dissertation is an examination of Divertimento for Solo Trombone and Wind Band by renowned wind band composer and conductor Jack Stamp. The result of this study is the illumination of a 21st-century composition for solo trombone and band that is made accessible for future performers, accomplished by constructing original musical exercises that are influenced by current trombone pedagogical materials that have either been edited, annotated or created by current performers and pedagogues such as Joseph Alessi, Brad Edwards and Michael Mulcahy. The piece also incorporates 20th -century American wind band influences. The careful selection of pedagogical materials serves the purpose of making this challenging solo accessible for the advanced academic trombonist and can serve as a template for surveying advanced literature of the present and future. Additionally, the pedagogical materials selected for use in this dissertation were considered based on their value in the present academic trombone repertory. Thus, this performance guide reflects on the validity of the modern trombone pedagogical literature to guide a performer's study, interpretation, and performance of a 21st-century work for solo trombone.

Le Rire de Saraï for flute and piano was written in 2001 by Guillaume Connesson. Although the composer's works have been commissioned and performed by numerous leading orchestras and musicians in Europe and the United States, his music is largely neglected by scholars. Despite the increasing popularity of Le Rire de Saraï, the piece also has never received scholarly attention. Therefore, an analytical study of the piece, its influences, and its context in Connesson's output will provide for a deeper understanding and informed performance of this significant element of the flutist's repertoire. Le Rire de Saraï, like much of the composer's music, is notable for the eclecticism of its language and its inspiration from an extramusical source. This study first discusses his biography, inspirational sources, and various musical influences, which provide essential background information to understand his musical world. This document then explores the story of Hagar and Sarah, which serves as the inspiration for the piece and how Connesson draws on the story without crossing into the domain of program music. Finally, the study examines the interactive elements of his eclecticism in the piece, such as French sensibility, American minimalism, Baroque toccata, and popular music.

John Mayer (1929-2004) was a British Indian composer and violinist. Despite his contributions to bringing Indian music to the West and his large output of works, the majority of his compositions remain largely unknown. This document focuses on Mayer's only oboe concerto, Shanai Awaz, which translates to "Sound of the Shanai" in Hindi. It is representative of his fusion of Indian and Western techniques. The performance guide helps the oboist navigate the fusion elements of the piece. Because no piano reduction of the score was made by the composer, the piece has likely not been performed since 1983. A piano reduction of the score was created as part of this dissertation to make it more accessible to oboists.
