The primary purpose of this thesis is to thoroughly discuss Hindemith's Sonata for Clarinet and Piano. In this work, Hindemith combine traditional writing techniques with the baroque and classical era, as well as modern technique known as the neoclassical style. The first chapter of this thesis discusses Hindemith's musical life along with many of his compositional styles. The second chapter explores his unique musical theories and creative concepts. The third chapter examines the background of this piece and its musical contents. The fourth chapter concentrates on the performance practice and interpretation aspect of the composition. I hope this research will help me develop better understanding of the piece and gain valuable knowledge for actual performances.
