This thesis delves into a comprehensive examination of the repertoire performed in the Senior Recital of Gavin R. Grove. In this study, selected works from Francis Poulenc (1899- 1963), Igor Stravinsky (1882-1971), George Gershwin (1898-1937) and Artie Shaw (1910-2004) undergo a musical analysis, with a specific emphasis on form, key and tonal relationships, rhythmic and melodic structures and any other pertinent musical concept present in these compositions. This thesis not only examines the musical aspects found in these works, but also provides a brief overview of each composer and the inherent stylistic characteristics present. This contextual background serves to enhance the overall comprehension of the pieces originally presented in the November 12, 2023 Senior Recital of Gavin R. Grove. Furthermore, this study provides a physical medium of analysis. Charts are presented to offer a visual representation of the musical structures and relationships explored throughout this thesis. This analysis of my Senior Recital repertoire aims to contribute insights into the works of these famed twentieth century composers, providing a greater understanding of the repertoire performed. This thesis will provide: 1) a biographical sketch of Francis Poulenc, Igor Stravinsky, George Gershwin and Artie Shaw, and 2) a formal analysis of the structure of each of the five works. I will conclude with a statement on the experimental nature of clarinet composition in the twentieth century.
