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.

Busoni's contribution to the art of the piano transcription is formidable. His chorale prelude transcriptions make him responsible for giving over to the piano repertoire a small portion of sacred literature. His special admiration of J. S. Bach, evidenced throughout his life, make Busoni's transcriptional practices all the more significant. Bach himself was a prolific transcriber of his own works and the works of others. This paper presents a brief history of keyboard transcriptional practices, emphasizing Busoni's methods by comparing the original works for organ with the transcriptions for piano. Four chorale preludes form the basis for this study: Ich ruf' zu dir, Herr Jesu Christ (BWV 639), Komm, Gott, Schopfer, Heiliger Geist (BWV 667), Nun komm' der Heiden Heiland (BWV 659), and In dir ist Freude (BWV 615).

Ignacy Feliks , a Polish composer active in Warsaw, is best known for having been a colleague of Frederic Chopin while they were both composition students of Jozef Eisner. As an early nationalist composer, Dobrzynski is examined within the context of nineteenth-century Warsaw's musical culture and political situation. Dobrzynski early training was provided by his father, who was Kapelmeister at the Ilinski court in Romanow. The most important achievements of the career which followed Dobrzynskifs move to Warsaw in 1825 include second place in an 1835 Viennese contest with the Second Symphony, a German tour in I8I8, and the directorship of the Teatr Wielki in 1852. Cast in the late eighteenth-centurv style, Dobrzynski two symphonies were composed in 1829 and 1831. These works show knowledge of Beethoven's music and exhibit Dobrzynski's skill at orchestration. Symphony No. 2 in C minor, Op. 15, is the more important work because of national elements in each movement, as well as its success in a Viennese symphony contest in 1835. Although a precedent for national elements is seen in studying the development of the Polish symphony in the eighteenth and early nineteenth centuries, Dobrzynski's contribution shows an intensification of musical patriotism which was inspired …
