Harmonic Highlights:
- Frequent ii-V progressions lead to temporary tonicizations, such as Dm7-G7-Cmaj7 (ii-V-I in C) and Cm7-F7 (ii-V in Bb).
- The progression incorporates minor iiø7-V7b9 cycles, specifically Cm7b5-F7b9, adding a darker harmonic color and suggesting temporary parallel minor tonality.
- Significant modulation occurs with Ebm7-Ab7 (ii-V in Db major), introducing harmonic material a tritone away from the F major tonic’s dominant.
- Secondary dominants (e.g., F7 as V/Bb) and altered dominant extensions (e.g., G7b9, F7b9) are liberally applied, expanding harmonic possibilities.
Improvisation Focus: Altered scales for dominant 7th chords.
Difficulty Rating: 4 (Advanced Intermediate) - The rapid succession of temporary modulations and altered dominant chords demands a high level of harmonic awareness and scale mastery.
