This dissertation consists of four programs: one lecture recital, two recitals for solo trumpet, and one in combination with other instruments and voices. The lecture was an exploration of the contents of Modo per Imparare a Sonare di Tromba, by Girolamo Fantini, published in 16358. Fantini, who was also a trumpet player, included in his volume a wide variety of music for the natural trumpet. In addition to military signals and fanfares, the book contains exercises for developing technical ability on the trumpet, a large number of dance pieces with and without accompaniment, duets for two trumpets, and sonatas for trumpet and keyboard.

The lecture was given on April 21, 1980. The problem with which this investigation is concerned is that of gathering information on the composer Johann Hummel, the performer Anton Weidinger, the keyed trumpet, for which the concerto was written, the concerto itself, and its ornaments, and in determining the correct performance practices of the ornaments. Sources written in the middle to late eighteenth century and from the first third of the nineteenth century gave valuable insight into the facts and attitudes concerning the composer, the performer, the instrument, and the concerto in question. Other information came from present day authorities writing in texts, periodicals, and reference works.

Hummel's Concerto for Trumpet (Concerto a Tromba principale) is overtly operatic and is stylistically reminiscent of Mozart's Don Giovanni. Using the methodology of Leonard Ratner and Wye J. Allanbrook, it is possible to explore gesture and rhetoric in Hummel's Concerto for Trumpet and Mozart's Don Giovanni, and achieve a deeper understanding of the stylistic similarities shared between the two works. In the third movement, dance is the most significant link to Don Giovanni. In the second movement, Hummel alternates between the emotions of Donna Anna and Don Ottavio as they appear in act 1, scene 13. The first movement makes extensive use of contrasting topics identified with buffa and seria characters to advance the musical narrative. Comparing Hummel's concerto and Mozart's opera is a hermeneutical approach that illuminates several performance practice implications. Knowing the expressive similarities and rhetorical strategies common to both works clarifies several issues, such as tempo, ornamentation, and above all, expression. Though Mozart's Don Giovanni and Hummel's Concerto for Trumpet are unequal in significance, it would be valuable to any interpretation of Hummel's concerto if the performer and audience acknowledge that the work is rhetorically and stylistically similar to Mozart's Don Giovanni.
