Structure -

__Head__ Theme played on trumpet, with tenor sax, playing an ocatve lower. Chords not on down betas to give elusive sense of pulse. Use 7ths, 9ths, 11ths and 13ths and chromatic harmonies. Use of alteration. short motif briefly developed the subsituted with new idea.

__Chorus 1__ Trumpet often plays away from basic chord progression - dissonent counterpoint. Use of walking bass in piano.. Subtle inflections of pitch played by double bass.

__Chorus 2__ Trumpet solo, vertuosic playing. Ghost not played in first beat of first bar, almost unaudable. Uses same chrod progression as all the other choruses.

__Chorus 3__ All choruses have a very improvisational feel, the song itself would vary in length everythime it was played.

__Chorus 4__ Trumpet uses half valve, a very difficult technique.
