Harmonic Highlights:
- Repeated II-V-I progression (Dm7-Gm7-C7-Fmaj7) firmly establishes and reinforces the F major tonality.
- The
F6chord variation substitutesFmaj7, a common jazz embellishment often used at phrase endings. - A iiø7-V7 progression (
Bm7b5-E7) temporarily tonicizes the Am7 (iii chord), creating a brief secondary dominant function within the F major context. - The
Am7-D7-Gm7-C7section functions as a clear iii-VI-ii-V progression, extending the dominant motion towards the final tonic.
Improvisation Focus: F Major Scale.
Difficulty Rating: 3/5. The tune features standard ii-V-I progressions with a common temporary tonicization, requiring solid grasp of diatonic harmony and modes.
