Harmonic Highlights:
- Prominent use of the vi-V/V (Gm7-C7) progression, creating a strong pull towards F major before resolving to Bb.
- The primary ii-V in Bb (Cm7-F7) is frequently altered with F7#5, introducing heightened dominant tension.
- A significant chromatic shift occurs with the descending ii-V chain: Fm7-Bb7 (ii-V of Eb) followed by Ebm7-Ab7 (ii-V of Db), exploring flat-side keys.
- Secondary dominants (G7) are employed to create further harmonic movement and lead to various temporary tonics.
Improvisation Focus: Targeting chord tones and guide tones through the numerous ii-V progressions and modulations.
Difficulty Rating: 4 (Intermediate-Advanced). The frequent chromatic modulations and altered dominant chords require a strong understanding of changing key centers.
