Harmonic Highlights:
- Frequent tonicization of the relative major (Ebmaj7) contrasting with the C minor tonic.
- Prominent use of secondary dominants (C7b13 leading to Fm7), creating temporary V/ii movements.
- Classic minor ii-V-i progressions (Dm7b5 - G7b9 - Cm7) firmly establish the C minor key.
- Altered dominant chords (C7b13, G7b9) introduce characteristic tension and color.
Improvisation Focus: Mastering the interplay between C minor and its relative major, Eb, is paramount.
Difficulty Rating: 4 (Advanced Intermediate). The shifting harmonic centers and altered dominant voicings require careful navigation.
