Harmonic Highlights:
- Features a standard diatonic Imaj7-vi-ii-V progression (Ebmaj7-Cm7-Fm7-Bb7) in the home key.
- Incorporates a strong ii-V-I progression to Ab major (bVI), Bbm7-Eb7-Abmaj7, providing a temporary tonal shift.
- Utilizes an extended minor ii-V-i (Em7b5-Am7b5-D7b9) to temporarily tonicize Gm (the mediant minor).
- Employs a chain of dominant 7ths (G7-C7-F7) that create momentum and lead towards the dominant of Eb.
Improvisation Focus: Navigating temporary tonicizations and ii-V changes with appropriate arpeggios and scales.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations and varied ii-V-i progressions demand adaptable harmonic understanding beyond basic diatonic playing.
