French Horn Sonata No. 1

Mvt 1 – Bop improvisers would often deploy phrases over an odd number of bars, and overlap their phrases across bar lines and across major harmonic cadences. Charlie Christian and other early boppers would also begin stating a harmony in their improvised line before it appeared in the song form being outlined by the rhythm section. This momentary dissonance creates a strong sense of forward motion in the improvisation and was one of the inspirations for the movements material.
