Harmonic Highlights:
- Frequent use of chromatic passing diminished chords (
E07,Gb07,A07) linking diatonic harmony. - The
Abm7 - Db7progression (ivm7 - bVII7) functions as a backdoor dominant, but resolves deceptively toGm7. - Secondary dominant
C7(V7/ii) clearly sets up theFm7(ii) chord. - Incorporation of an altered dominant (
Bb7#5) adds tension before the final resolution.
Improvisation Focus: Altered and Diminished scales.
Difficulty Rating: 3 (Intermediate). It features diatonic progressions enhanced by frequent chromatic diminished passing chords and secondary/altered dominants, requiring careful navigation.
