This project's goal is to expand the repertoire for soprano saxophone featuring improvisation. Each work detailed in this document features improvisation as an integral component. The first piece, Impetus, was written by Grant Jahn for soprano saxophone and piano. The second piece, Sonata, was written for the same instrumentation by Brett Wery. Ethan Cypress wrote the third work for solo soprano saxophone, Noir et Bleu. The final composition on the project, Counterpunch by Gregory Wanamaker, was written for saxophone sextet. This paper also includes composer biographies, program notes, performance guides, and composer questionnaires. The central component of this project is a recording of all these works which features the author.
