Harmonic Highlights:
- Frequent
iiø7-V7-iprogressions (e.g.,Dm7b5-G7-Cm7) firmly establish and reinforce the C minor tonic key. - Utilization of diminished chords like
Db07(functioning as a chromatic passing chord or substitute dominant) andB07(acting as a rootlessG7b9). - The
Ebm7-Ab7progression introduces modal interchange, creating a ‘backdoor’ dominant feel or aii-Vfrom the parallel major before resolving. - A classic
ii-V-Iin the relative major (Fm7-Bb7#9-Ebmaj7) provides harmonic contrast and a temporary resolution point.
Improvisation Focus: C Harmonic Minor scale and its derived modes (e.g., G Phrygian Dominant for G7) for navigating minor ii-V-i resolutions and altered dominants.
Difficulty Rating: 3 (Intermediate). The tune combines standard minor ii-V-i movements with chromatic diminished chords, altered dominants, and modal interchange, requiring harmonic agility.
