Harmonic Highlights:
- The recurring F#m7b5 - F7#11 - Am progression provides a distinctive, non-diatonic turnaround to the tonic minor, with F7#11 functioning as a colorful backdoor dominant or tritone substitute.
- The use of Am7/G creates a smooth, descending chromatic bass line (A-G-F#-F) into the F#m7b5, enhancing voice leading in the primary vamp.
- The prominent F7#11 chord introduces a Lydian Dominant sound, adding a sophisticated, modern jazz flavor over the bVI dominant.
- Sections with successive dominant chords (A7, D7) indicate temporary modulations or a blues-influenced progression, contrasting with the initial minor key center.
Improvisation Focus: Navigating the Lydian Dominant scale (F Lydian b7) over F7#11 is paramount for capturing the song’s signature sound.
Difficulty Rating: 4 (Advanced). The frequent non-diatonic turnarounds and the application of specific scales over altered dominant chords require an advanced understanding of jazz harmony.
