Harmonic Highlights:
- Alternates between C minor ii-V-i and tonicizations of its relative major, Eb.
- Features a distinctive
Ab7(bVI7) toG7(V7) progression, injecting blues tension into the minor key. - Utilizes an extended cycle of descending dominant 7th chords (
C7-F7-Bb7-Eb7-Ab7). - Culminates in a dramatic arrival at
Dbmaj7(bIImaj7), establishing a temporary Neapolitan-like tonic.
Improvisation Focus: Fluid command of altered scales and arpeggios to navigate rapid dominant cycles.
Difficulty Rating: 5 (Advanced). The extended dominant chord chain and multiple rapid modulations demand sophisticated harmonic comprehension and agile execution.
