The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other avenues of register development. If registers are laryngeally derived, there should be another way of register unification, which directly addresses the coordination of the laryngeal muscles. In support of this argument, this thesis investigates the teaching practices of a group of twentieth-century American voice teachers, who rely on intensity manipulation as the primary means for enhancing the register adjustments. Intensity exercises such as the messa di voce has long been practiced in historical pedagogy, but it is not until now that voice science confirmed its significance in register coordination.

Richard Strauss's Duett-Concertino for Clarinet and Bassoon with Strings and Harp, AV 147 was one of the last works written by this celebrated composer. This double concerto has been largely unrecognized by performers and scholars until a recent surge in recorded performances. Some factors that hinder performances of the Duett-Concertino include unusual scoring and difficult rhythmic passages, as well as a lack of acknowledgement or understanding of the programmatic elements represented in the music. Sketches and letters show that the Duett-Concertino was inspired by a fairytale, which may have been the popular Beauty and the Beast. The programmatic analysis in this study examines the musical gestures of the piece, which, when combined with the cues provided in the sketches and letters, construct a musical interpretation of the fairytale. Recognition of the extra-musical features of the Duett-Concertino is essential for an effective performance and, in turn, creates additional performance possibilities such as narration and choreography.

This work discusses in detail the history of, and processes associated with the construction of baroque era trumpets then and now. The work addresses metallurgy, tools, construction methods, and playing characteristics of instruments built with old techniques and modern techniques.

The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988). Histories of each composition are chronicled. An analysis of formal organization and significant style features examines musical structure, harmonic language, rhythmic character, instrumentation, …

This document examines Frank Ferko's unique setting of the ancient Latin sequence, Stabat Mater that incorporates five English interpolations dealing with the subject of parental grief over the loss of a child. The twenty Latin stanzas and five English interpolations are examined harmonically and philosophically, as two separate works. The tonal architecture of the work, outlined in two large arches built on key relationships, is explored in the body of the paper in addition to a graphic depiction and table of key centers. The interrelationship between key centers and textual considerations is examined. An extensive interview with the composer provided invaluable information regarding the creative process as it relates to the choice of English texts, compositional techniques and influences, and the stylistic musical diversity that characterizes the work. Three prominent American conductors, who have conducted significant performances Stabat Mater discussed specific problems and solutions in preparing and performing the work. Data pertaining to Stabat Mater history and other settings was gathered from reference materials, periodicals, and internet sources.

The transcription is an addition to the repertoire for brass ensemble and bass trombone. Consideration is given to the nineteenth-century orchestration treatises of Berlioz and Strauss as well as the twentieth-century texts of Erik Leidzén, Walter Piston, and Samuel Adler. The transcription process is shaped by the principles of these writers. The score is contained in the appendix.

Chen Yi's music is well accepted and recognized nationally and internationally through an increasing number of commissions and performances. Major symphony orchestras, choruses, institutions and companies request her compositions on many occasions in order to increase understanding and exploration of Chinese influences on western classical idioms. This study provides the first detailed discussion of her compositional mastery and her fusion of Chinese music with the language of western choral traditions. Chen Yi's reputation as a prominent orchestral composer does not restrain her passion to apply instrumental techniques and materials to her quality choral compositions. This study focuses on (1) how hardship and various life experiences during the ten-year Cultural Revolution shaped Chen Yi's musical inspirations; (2) how the influences of major musical genres, such as traditional Chinese folksong, jingju, model play, 19th-20th century nationalism, impressionism, and serialism are consolidated in her kaleidoscopic compositional techniques; and (3) the application of Chinese languages, pedagogical concepts, and extra-musical elements, such as Chinese poems, paintings, and calligraphies, revealed in her original, intelligent and resourceful choral creations.
