The dissertation consists of four recitals: three solo recitals and one lecture recital. The repertoire of all the programs contained both music written specifically for the trombone and transcriptions from various other instruments. The lecture recital, "J. s. Bach's Six Suites for Solo Violoncello, BWV 1007-1012? Their History and Problems of Transcription and Performance for the Trombone," was presented on June 20, 1983. The lecture was an attempt to illuminate the rationale and performance problems of transcribing the Bach 'cello suites to the modern tenor trombone with an F attachment and also to provide background information on the suites and the early solo emergence of the violoncello. The program included the performance of the Suite No. 2_ in d minor, BWV 1008, with the movements: Prelude, Allemande, Courante, Sarabande, Minuets I and II, and Gigue.

The dissertation consists of four recitals: three solo recitals and one lecture recital. The repertoire of all the programs was intended to demonstrate a variety of music written originally for trombone. The lecture recital, "The Trombone in German and Austrian Concerted Church Music of the Baroque Period," was presented on July 3, 1974. The lecture was an attempt to illuminate the position of the trombone, both as an ensemble instrument and as a solo obbligato instrument, in church music of the Baroque period. The program included the performance of two works by Heinrich Schutz for bass voice, four trombones, and continuo; one work by Andreas Hammerschmidt for alto, bass, trombone, and continuo; and one work by Johann Joseph Fux for soprano, trombone, two violins, and continuo. A line of influence was traced from the Venetian composers Giovanni Gabrieli and Claudio Monteverdi, through Schiitz, Hammerschmidt, and Fux, to Mozart.

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.

This dissertation consists of three solo recitals and one lecture recital. The repertoire of all programs is composed of music written specifically for the trombone plus two transcriptions of works for voice. The purpose of this paper is to investigate the use of selected vocal pedagogical material as a means of developing musicianship for the trombonist. The historical relationship of the voice and the trombone is traced through written documentation and musical composition. Similarities between the development of legato technique for the vocal student and the trombonist are examined. A brief history of the vocalise and its pedagogical function is presented. The development of expressive musical performance for the trombonist is explored through the use of examples from three different vocalises of Marco Bordogni.
