Harmonic Highlights
- The initial I-VI7-ii-V progression (Bbmaj7-G7-Cm7-F7) firmly establishes the home key’s functional harmony.
- An extended cycle of dominant 7ths (D7-G7-C7-F7) creates strong directional tension resolving to the tonic Bbmaj7.
- A blues-influenced dominant chain (Bb7-Eb7-Ab7) briefly introduces temporary tonicizations before pivoting to the longer cycle of fifths.
Improvisation Focus Navigating extended dominant cycles using Mixolydian scales and their alterations.
Difficulty Rating 4 (Advanced) - The rapid succession of dominant 7th chords in both bluesy chains and extended cycles demands quick harmonic recognition and scale application.
