- Frequent use of dominant sus4 chords (Eb7sus, Gb7sus) creates a “floating” tonality that delays resolution to the Ab major tonic.
- Chromatic approach movement, specifically the D7 to Dbmaj7, utilizes tritone substitutions to soften transitions between diatonic functions.
- The progression relies on secondary dominant cycles (C7–F7–Bbm7) to bridge the relationship between the relative Ab major and the F minor tonic.
- Extensive use of altered extensions (b9, b13) on dominant chords facilitates sophisticated voice leading in the turnaround.
Improvisation Focus The Ab Major/F Minor scale relationship, specifically navigating the frequent chromatic dominant substitutions.
Difficulty Rating 3/5 - While the tempo is often rubato or a ballad, the non-functional dominant chords and constant key-center shifting require advanced harmonic awareness.
