These four sonatas of William Flackton (1709-1798) are probably the earliest collection of sonata literature written for the viola. They exist with a few other string sonatas from the Baroque period in England. It is essential to establish their place in English baroque music and to develop a performance milieu or stylistic preference that leads up to and lasts through the time span of Flackton's sonatas. The final tool to establish an interpretive plan will be to present a general analysis of the four sonatas with special emphasis on the D major sonata (opus 2, no. 4).

French trumpet works comprise a large portion of the contemporary standard repertoire for the instrument, and they frequently present unique stylistic and interpretive challenges to performers. The study establishes the influence of jazz upon Henri Tomasi, André Jolivet, Eugène Bozza and Jacques Ibert in their works for solo trumpet. Idiomatic elements of jazz style are identified and discussed in terms of performance practice considerations for modern-day trumpeters.
