Harmonic Highlights
- The Db07 chord (bIIIdim7) consistently functions as a substitute for G7b9 (V7b9/ii), introducing chromatic tension before resolving to Cm7.
- An unexpected Eb7 (bIII7) progression to Dm7 (iii) introduces a momentary non-functional dominant resolution, challenging diatonic expectations.
- The recurring F7sus4 resolving to F7 provides a classic Vsus-V motion, enhancing the dominant pull to Bbmaj7.
Improvisation Focus Diminished scale application over the Db07 chord.
Difficulty Rating 4 (Upper Intermediate) due to the frequent chromatic diminished chords and non-standard dominant resolutions requiring specific scale choices and harmonic foresight.
