Harmonic Highlights:
- The
Ab07chord functions as a chromatic passing diminished, creating tension between the tonicFmaj7and theGm7(ii chord) in the A section. - An extended cycle of dominant 7th chords (
F7-Bb7-Eb7-Ab7) is a prominent feature, driving the progression through several temporary keys before resolving to the V (C7). - The
F7at the beginning of the B section strongly tonicizesBbmajor, initiating a modulation through a sequence of secondary dominants.
Improvisation Focus: Navigating extended dominant cycles with Mixolydian modes and their alterations is crucial.
Difficulty Rating: 4 (Advanced Intermediate) The rapid changes through multiple temporary key centers via an extended dominant chord progression demand a high level of harmonic agility.
