- Rapid alternation between ii-V-I progressions in Eb Major and ii-V progressions in F minor, creating a shifting tonal center between the tonic and the subtonic.
- Structural reliance on the C7b9 altered dominant to provide a strong Phrygian Dominant pull toward the F minor tonic.
- Incorporation of the relative major (Ab Major) through Bbm7-Eb7 sequences during the bridge to offer harmonic contrast and relief from the minor tonality.
Improvisation Focus Targeting guide-tone resolutions (specifically navigating the Ab in F minor versus the G in Eb Major) to articulate the shifts between the two primary keys.
Difficulty Rating 3/5: The progression uses standard jazz cells, but the performer must skillfully manage the frequent pivots between F minor and Eb Major tonal centers.
