The dissertation consists of four recitals: one chamber music recital compiled from two years' series of chamber music performances in residence, two solo recitals, and one lecture recital. The repertoire of these programs was chosen with the intention of demonstrating the capability of the performer to deal with problems arising in works of varying types and of different historical periods. The lecture recital, The Fifth and Sixth Clarinet Concertos by Johann Melchior Molter, begins with perhaps the first performance of the Concerto No. 4 in D Major, Mus. Hs. 337, for clarinet in D with orchestral accompaniment reduced for piano. Bibliographical, historical and technical information is marshaled to justify the solo designation of Badische Landesbibliothek concerto manuscripts 334 and 328 to D clarinet rather than clarino. An investigation into the formal and stylistic aspects shows these two questionable works to be comparable to the composer's other four clarinet concertos. The analysis is followed by a short discussion of the problems involved in the transcription and performance of the works. The lecture concludes with the first performance of the Concerto No. 6 in D Major, Mus. Hs. 328, for clarinet in D with orchestral accompaniment reduced for piano.

The problem with which this investigation is concerned is that of developing a theory in vocal pedagogy, voiception, which could provide teaching techniques with tangibility for gaining control of both voluntary and involuntary functions of the singing act. This study appears to show that feeling tone and cognition are innately involved with singing, since the vocal instrument is actually a part of the singer. Analysis of the sung vowel through the singing sensation is the connecting link for gaining control of involuntary vocal functions.
