Harmonic Highlights:
- The progression commences with Gmaj7 as the ostensible tonic within a declared G minor key center, creating a characteristic Monkian major-minor harmonic ambiguity.
- A sequence of modal interchange dominant 7th chords (F7, Eb7) provides a bluesy, non-diatonic flavor before the traditional V7.
- The roots of the dominant-type chords (F-Eb-D) feature a descending whole step followed by a half step, culminating in the functional D7 (V7).
- Despite the non-traditional tonic and preceding dominant qualities, the D7 strongly resolves to G, anchoring the harmony to the overall G minor key.
Improvisation Focus: Navigating the parallel major-minor tonic ambiguity.
Difficulty Rating: 4 (Advanced) – The harmonic structure presents advanced challenges due to the non-diatonic Gmaj7 tonic and the quick succession of modal interchange dominant 7th chords.
