Harmonic Highlights:
- Prominent use of the ii-V-I progression (Fm7-Bb7-Ebmaj7) as a foundational harmonic device.
- Tonicization of the subdominant (Ab) through a ii-V progression (Bbm7-Eb7-Ab6).
- The
F7chord functions as a secondary dominant (V7/ii), creating tension before the ii minor chord. - Inclusion of the
B7chord introduces significant chromaticism, likely functioning as a tritone substitute or a distant chromatic dominant.
Improvisation Focus: Fluent application of arpeggios and scales over ii-V-I progressions and tonicizations.
Difficulty Rating: 4 (Advanced Intermediate). The rapid modulations, secondary dominants, and significant chromaticism require a sophisticated harmonic understanding.
