Harmonic Highlights:
- The prominent bVII7#11 (Ab7#11) functions as a recurring backdoor dominant or Lydian Dominant leading to the tonic Bbmaj7.
- Secondary dominants (G7, C7) create dominant chains (V/ii, V/V) leading towards the tonic’s dominant and resolution.
- Features an altered dominant V (F7#5) and a chromatic minor chord (Ebm6), adding tension and unique color.
Improvisation Focus: Navigating altered dominant scales (e.g., Lydian Dominant for Ab7#11, Altered for F7#5).
Difficulty Rating: 3 (Intermediate-Advanced) because it requires navigating frequent secondary dominants, altered chords, and unique chromatic movements like the bVII7#11 and Ebm6.
