The lecture recital was given April 16, 1971. An Excellent Meane, six settings of Gloria Tibi Trinitas, Eterne rerum conditor, and Te Deum laudamus by William Blitheman, In Nomine by John Taverner, and Ecce tempus idonem by Thomas Tallis were performed, together with a choir of four men's voices, following a lecture on various aspects of organ music in early Tudor England. In addition to the lecture recital, three other public recitals, all solo programs, were performed. The first solo recital, including works of Dietrich Buxtehude, Johann Sebastian Bach, Paul Hindemith, and Max Reger, was performed on March 14, 1971. On October 23, 1972, the second solo recital was performed. The program included compositions by Olivier Messiaen, Johann Sebastian Bach, Cesar Franck, and Charles-Marie Widor. On October 17, 1977, the third solo recital, including works by Johann Sebastian Bach, Girolamo Frescobaldi, Johann Jacob Froberger, Dietrich Buxtehude, James Hathaway Tallis, and Maurice Durufle, was performed. The four programs were recorded on magnetic tape and are filed with the written version of the lecture as a part of the dissertation.

The lecture recital was given July 18, 1977. The lecture began with the performance of the Three Preludes and a discussion of these final works in relation to the composer's last period of composition which included the Sonata for Piano. After the biographical foundation was laid, the Sonata for Piano was detailed concerning form and compositional techniques. All works were performed from memory. In addition to the lecture recital, three public recitals were performed. The first solo recital, performed on August 11, 1975, consisted of works by Schubert and Liszt-Busoni. The second recital, a chamber recital, performed March 29, 1976, consisted of solo and chamber works of Messiaen. The final solo recital, performed on August 1, 1977, consisted of works by Clementi, Satie, and Rubinstein. All four programs were recorded on magnetic tape and are filed, along with the written version of the lecture recital, as part of the dissertation.

The lecture recital was given on July 25, 1977. Transcriptions and arrangements for clarinet and piano of nineteenth-century Italian opera were popular during the virtuoso wind era and are representative of an important phase in the history of clarinet playing. Arias of Rossini and Verdi and a fantasia based on Rigoletto were performed during the lecture recital. In addition to the lecture recital, three other public recitals were performed, including solo compositions for clarinet and chamber works including clarinet.

The purpose of this study was to investigate the phenomenon of choral blend through acoustical analysis of individual vocal sounds. One aspect of the study involved identifying and comparing the acoustical qualities of sounds produced in the usual solo manner and sounds produced by the same singers attempting to blend with a unison ensemble. Another aspect of the study involved identifying and comparing the acoustical qualities of vocal sounds identified as blending well and poorly with a unison ensemble. Singers attempting to blend adjust their overall intensity not only to affect the perceived loudness of their tones, but also to facilitate other acoustical changes which are helpful for achieving blend. Vocal blend apparently may be achieved more readily on vowels having few upper partials than on vowels having numerous upper partials. Where vibrato is employed, certain vocal sounds can achieve a good blend even though their fundamental frequencies only approximate the theoretically correct frequency. There apparently is an interaction between the vibrato of a vocal tone and its spectral features, making it advantageous for the singer to adopt mutually beneficial approaches to both factors in order to blend. Vowel modification effective for achieving vocal blend- -at least for sopranos-- appears …

The problem was to survey and collect ideas on the use of improvisation as a teaching and learning tool in elementary piano instruction and to prescribe activities and exercises for second through fourth grade piano classes. These areas were examined: philosophies and theories influencing traditional instruction, effects of creative keyboard activities on children's musical development, specific teaching strategies using improvisation, evaluative procedures, and suitability of materials for young children. Data collected from published and unpublished materials were classified, and presented concerning the feasibility of using keyboard improvisation with early elementary children. It was found that suitable improvisational exercises allow the child to organize his perceptions into the basic concepts of music. Recommendations for teachers and researchers were made.

This paper presents a means of modulating timbre in digital sound synthesis using additive processes . A major portion of the paper is a computer program, written in Pl/1, which combines this additive method of timbre modulation with several other sound manipulation ideas to form a compositional program. This program-which is named CART for Computer Aided Rotational Translation-provides input for the Music 360 digital sound synthesis program. The paper contains three major parts: (1) a discussion of the CART program's evolution; (2) a manual describing in detail the use of CART; and (3) two tape compositions realized using the program. An appendix contains the program listing and listing of the input cards that were used to produce the two compositions.
