Harmonic Highlights:
- Features frequent ii-V-I progressions in F major (e.g., Gm7-C7), establishing a strong tonal center throughout the form.
- Incorporates the Eb9 (bVII9) as a colorful non-diatonic dominant, adding a ‘backdoor’ flavor or unexpected resolution to Am7.
- Utilizes a classic viiø7-V7/vi-vi (Em7b5-A7b9-Dm7) progression, effectively tonicizing the relative minor (Dm).
Improvisation Focus: Navigating dominant and minor arpeggios, Mixolydian over V7 chords, and Dorian/Aeolian over minor chords is paramount.
Difficulty Rating: 3 (Intermediate) - While core progressions are common, the non-diatonic Eb9 and the G7-C7-Cm7 sequence introduce harmonic twists requiring careful attention.
