Charlie Parker’s three improvisatory choruses in Parker’s mood (1948) can be viewed as one statement; the first is introductory, the second climactic, and the third provides a summary by repeating previous material.

Parker’s palette of resources includes the blues scale, stock blues melodic figures, bebop-style scale runs, arpeggiated figures derived from substitute progressions, idiosyncratic articulation, and a historic tradition of improvisation.
