This investigation surveys pertinent literature, from 1917 to 1982 inclusive, regarding artistic vibrato and tremolo in singing. The contents are subdivided into individual investigative reports by various vocal researchers. Due to mounting confusion within the amassed literature, the need for systematic organization and evaluation is evident. Misunderstandings within the context of the literature and misnomers within the terminology require clarification and resolution. The evaluation intends to produce a proper perspective on vibrato and tremolo, eradicating some of the confusion surrounding the terms. Artistic vibrato is recognized as a desirable component in Western vocal music. In contrast, tremolo is deemed a deviant vibrato, i.e., a vibrato which deviates from artistic norms. The study attempts to clarify the distinguishing traits of these two vocal phenomena.

Chronomorphosis is a chamber ensemble piece for flute, clarinet, viola, cello, piano, and percussion. The work, comprising three movements is approximately fourteen minuted in duration. One of the most apparent characteristics of the work is its progression from non-metrical time organization involving aleatoric elements to metrical time organization involving changing meters but no aleatoric elements. The Pitch set is a constant element throughout the piece. The instrumentation selected exhibits a variety of color in all ranges: the flute in the upper register, the clarinet, viola, and vibes in the middle register, and the cello and the timpani in the lower register, the piano having access to all registers.

Joseph Fiala (1754-1816) was a composer and performer of the classical period. His many compositions include manuscripts of a concerto for clarinet, taille, and orchestra in the Fürstlich Thurn und Taxis Hofbibliothek in Regensburg, West Germany and the Library of Congress in Washington, D.C. , U.S.A. This paper identifies the instrument called "taille" as the English horn and discusses the work in areas of form, harmony, rhythm, orchestration, and use of solo instruments. Comparison with contemporary works shows the piece is typical of the eighteenth-century symphonie concertante and, together with the composer's manuscript, provides a basis for editing of the solo parts.
