Harmonic Highlights
- Frequent secondary dominants like D7 (V/V) and E7b9 (V/Am) introduce chromaticism and temporary tonicizations beyond the C minor diatonicism.
- A clear ii-V-I modulation to the relative major (Eb major) via Fm7-Bb7-Eb6 provides a major-key resolution before returning to the minor tonic.
- The use of G6 as the V chord and Eb7 (bIII7) introduces harmonic ambiguity, hinting at blues elements or tritone substitutions within the progression.
Improvisation Focus Arpeggios outlining the prevailing chords and their extensions.
Difficulty Rating 4 (Advanced Intermediate) - The frequent secondary dominants, clear relative major modulation, and altered dominant chords demand flexible harmonic awareness and diverse improvisational strategies.
