Harmonic Highlights
- The progression frequently features a
iii-VI-ii-V(Am7-D7-Gm7-C7) leading to the tonic, withD7functioning as a secondary dominant (V/ii). - A sudden chromatic
ii-Vprogression,Abm7-Db7, introduces an abrupt “side-slip” or temporary tonicization to Gb major, creating harmonic tension. - The piece consistently returns to the diatonic
ii-V-I(Gm7-C7-Fmaj7) in F major after moments of harmonic deviation, solidifying the home key.
Improvisation Focus Navigating both diatonic F Major harmony and abrupt chromatic ii-V substitutions.
Difficulty Rating
3 (Intermediate). The core progressions are standard, but the abrupt chromatic ii-V (Abm7-Db7) requires quick harmonic recognition and adaptation.
