- Modal Borrowing: The ii-V (Fm7-Bb7) temporarily borrows from F minor or tonicizes Eb major, creating a significant departure from the F major key center before resolving back.
- Secondary Dominant Function: Prominent use of D7b9 as a V7/ii, intensifying the drive towards the Gm7 (ii) chord within the prevailing F major harmony.
- Chromatic Passing Diminished: The Ab07 chord functions as a striking chromatic passing diminished, adding tension and color between Am7 and Gm7 and requiring careful harmonic navigation.
Improvisation Focus: Arpeggio outlining to define chord changes and guide tones.
Difficulty Rating: 3 (Intermediate) - The tune blends standard ii-V-I progressions with secondary dominants and a chromatic passing diminished chord, requiring careful harmonic awareness.
