The dissertation consists of four recitals. Three solo recitals featured a variety of selected works for bass trombone and piano by traditional and contemporary composers. The lecture recital, entitled "The Trombone in German and Austrian Ensemble Sonatas of the Late Seventeenth Century," is a study which examines the role of the trombone, both as a solo and ensemble instrument, and the functions of the instrument in ensemble sonatas of the late seventeenth century. The trombone's use in instrumental ensembles was traced from the fifteenth century to the present. The program included selections by German composers Daniel Speer and Matthias Weckmann, and Austrian composers Autonio Bertali, Johann Heinrich Schmelzer and Heinrich Ignaz Franz Biber.
