A comparative analysis of the musical transcriptions of Dorothy Ashby with those of her predecessors proves that Ashby was a uniquely powerful and innovative influence on the genre of jazz harp. This dissertation begins with a summative biography of Ashby, following her education in both jazz and classical music through to her career highlights as a performer, arranger and composer. An analysis of Ashby's recordings reveals the development of her groundbreaking musical style throughout her life. This paper also examines Ashby's social activism through musical theatre, especially with regards to combating racism. Next, a brief biography of jazz harp forerunners Casper Reardon and Adele Girard precedes a comparative analysis of Reardon's "Aint' Misbehavin" with Ashby's "Soft Winds" and a comparative analysis of Girard's "Harp Boogie" with Ashby's "Blues for Mr. K." Finally, myriad examples of current musicians covering and sampling her work confirm the paramount and lasting influence of Dorothy Ashby's music.

The link between trumpet playing and emulation of the human voice has been acknowledged by a number of prominent teachers, authors, and composers since the inception of the trumpet as a melodic instrument. This dissertation is a pedagogical guide to lyrical trumpet performance based on the verismo style of singing consistent with the authentic interpretations of operatic soprano arias by Pietro Mascagni, Ruggero Leoncavallo, and Giacomo Puccini. Included are chapters that examine various aspects of the verismo style, as well as comparison and application of late 19th-century voice pedagogy to trumpet practice and performance. This resource examines six recordings of sopranos who created or popularized operatic roles during the verismo period. Included are transcriptions of the six arias for trumpet and piano, with performance notes based on dramatic and textual contexts, as well as interpretive aspects, namely tempo, dynamics, and vibrato.
