bebop

A jazz style that emerged in the 1940s characterised by fast tempi, virtuosic technique, complex chromatic chord progressions, and long improvisation-like melodic lines that weave through the harmony.

Kapustin's fast passagework frequently mimics bebop improvisation lines. Play them with forward momentum and slight rhythmic flexibility, as a jazz soloist would phrase a run — propelling toward target notes rather than playing each note with equal weight.
