This study investigates the pedagogical applications of scat-singing within the jazz trombone studio. In addition to the obvious ear-training benefits that the student player can gain from this synthesis, the palette of articulation subtleties and overall musically expressive qualities for trombonists can also be greatly enhanced. These commonalities will encompass the pedagogical focus of this document, utilizing performance recordings and publications by prominent jazz artists and writers to document existing teaching strategies as well as develop new concepts. The first section of this document presents an introduction that includes a historical overview of scat-singing, prominent scat-singing instrumentalists, and concepts and current literature. The second section presents selected biographies on Wycliffe Gordon and Bill Watrous, both prominent jazz trombonists who sing as well as play the trombone. The third section investigates jazz articulation, scat-singing articulation, and doodle-tongue articulation and their relevance to this topic. The fourth section explores musically expressive qualities as analyzed in Bill Watrous’ solo transcription of “Body and Soul.” The final section draws conclusions about the pedagogical applications of scat-singing within the jazz trombone studio and summarizes current teaching strategies. Although this document is not a performance guide, an informed performance of the concepts and examples contained herein is required.

This study examines the evolution of Ella Fitzgerald's scat syllable vocabulary during a key developmental period in her career when she was recording for Decca Records. Between 1943 and 1952, Fitzgerald established the syllabic vocabulary that would serve as a defining characteristic of her improvisational style for the rest of her career. Fitzgerald is commonly praised as the greatest vocal improviser in jazz history, but while much has been written about Fitzgerald's melodic and harmonic approach to jazz improvisation, little has been written about her syllabic approach. Timbre and articulation are considered to be vital elements of any jazz musician's style; the study examines the changes in Ella Fitzgerald's syllabic approach through transcription and analyses of thirteen scat solos recorded during this time period, using scat syllable choices to discuss timbre and articulation. This analysis provides a model for further research of its kind, as well as informing historically accurate performance practice by both teachers and students of jazz singing.
