Harmonic Highlights:
- Frequent deployment of secondary dominants (C7, A7#9) and non-diatonic dominants (Bb7, B7) creating temporary tonal shifts and unexpected resolutions (e.g., Bb7 to Em7).
- Prominent use of altered dominant chords (G7#5, A7#9, C7#5) to enhance tension and lead effectively to subsequent chords.
- Brief, yet clear, modulation to the subdominant key of F major via a ii-V progression (Gm7-C7#5).
Improvisation Focus: Dominant altered scales and chord tone outlining.
Difficulty Rating: 4 (Advanced Intermediate) - Requires adept navigation of complex harmonic substitutions and non-diatonic dominant resolutions.
