Harmonic Highlights:
- The prominent use of the
Ab7(bVI7) as a “backdoor dominant” resolving to the tonicC6provides a distinct bluesy flavor. - A descending chromatic diminished chord,
Eb07, acts as a passing harmony betweenEm7(IIImin7) andDm7(ii). - An extended cycle of dominant chords (
E7 - A7b9 - D7 - G7b13) functions as a series of secondary dominants, building tension toward the tonic.
Improvisation Focus: Altered Dominant Scales.
Difficulty Rating: 4 (Challenging) Explanation: Navigating the non-diatonic backdoor dominant, passing diminished, and the extended altered dominant cycle requires strong harmonic awareness and scale proficiency.
