Harmonic Highlights:

  • Frequent use of ascending chromatic diminished chords (B07, C#07) linking diatonic major and minor chords.
  • Prominent use of the backdoor dominant progression, notably Abmaj7#11 resolving to Bbmaj7 (bVIImaj7#11 to I).
  • Strategic tritone substitutions occur, as seen with E9 (subV7/IV) resolving to Ebmaj7.
  • Altered dominant chords like D7#5 provide colorful extensions and lead to various resolutions.

Improvisation Focus: Bebop scales and arpeggios, specifically emphasizing altered dominant and diminished sounds.

Difficulty Rating: 5 (Advanced) due to the rapid harmonic rhythm, frequent non-diatonic movements, and complex altered dominant and diminished chord types.
