Harmonic Highlights

  • Frequent minor ii-V-i sequences (Gm7 - A7b9 - Dm7) reinforce a strong D minor tonal center using classic bebop functional harmony.
  • Use of secondary dominants (E7 leading to A7) creates V/V to V motion, introducing chromaticism before resolving to the tonic.
  • Highly altered dominant chords (A7#9, A7b13) provide a dense, dissonant palette that defines the Bud Powell “Bud-ism” sound.
  • Rapid harmonic rhythm requires navigating cadential points every two beats, demanding precise vertical alignment at high velocities.

Improvisation Focus D Harmonic Minor and the Altered Dominant scale (Super Locrian).

Difficulty Rating 5. The extreme tempo combined with dense minor-key changes requires virtuosic technique and an advanced command of bebop vocabulary.
