Harmonic Highlights:
- Prominent use of secondary dominants (D7, A7b9) and an altered dominant (G7#5) to create tension and drive towards target chords.
- Features a significant modulation to the distant key of Ab major (bVI) established by a clear IIm7-V7-I progression (Bbm7-Eb7-Ab6).
- Employs a chromatic diminished chord (F#07) resolving to an inverted tonic (C6/G), adding color and sophisticated voice leading.
- The harmonic journey concludes with a IIm7-V7 (Am7-D7) sequence, preparing the return to the tonic C major.
Improvisation Focus: Chord tone improvisation across distinct key centers and altered harmonies.
Difficulty Rating: 4 (Advanced Intermediate) - The significant modulation to Ab major and the inclusion of altered dominants and chromatic chords demand harmonic flexibility and awareness.
