Harmonic Highlights
- The prominent use of F7 (I7) instead of Fmaj7 establishes a strong blues-inflected tonic dominant sound throughout the form.
- The B07 chord functions as a chromatic passing diminished, creating a brief tension point before resolving to the F7 tonic.
- Extended ii-V progressions, such as Am7-D7-Gm7-C7, provide characteristic bebop harmonic drive through sequential dominant resolutions (ii-V of ii, then ii-V of I).
Improvisation Focus Precise chord tone outlining over fast-moving ii-V-I progressions.
Difficulty Rating 5 (Advanced) - The rapid harmonic rhythm, frequent dominant substitutions, and intricate ii-V-I progressions demand highly developed technical and harmonic fluency.
