Harmonic Highlights
- Persistent use of the IV7 chord (Bb7) creating a blues-inflected tonic prolongation or deceptive resolution.
- Standard ii-V-I (Gm7-C7-Fmaj7) progression firmly establishes the tonic key.
- Inclusion of the vi-ii-V (Dm7-Gm7-C7) turnaround provides common harmonic motion leading to the tonic.
Improvisation Focus F Major scale, adapting to the recurring IV7 (Bb7).
Difficulty Rating 3/5 - The mix of diatonic harmony with a prominent, recurring IV7 chord presents moderate challenges for improvisation beyond basic major scale application.
