- Chains of secondary dominants (e.g., D9-G9-C7 leading to Fmaj7) create rapid, albeit temporary, tonicizations.
- Frequent modulations to distant keys (e.g., implied shifts towards F major, C major, and E major) challenge a static tonal center.
- Classic minor key resolutions, such as the vii°7 (G#°) to the tonic minor (Am7), anchor the home key amidst chromaticism.
- Incorporation of altered dominants (G7b9, D13) and non-diatonic major chords (Emaj7) adds sophisticated color and tension.
Improvisation Focus: Navigating the rapid chord changes with arpeggios and appropriate altered scales over dominant functions.
Difficulty Rating: 4 (Advanced). The constant harmonic movement, dense dominant structures, and distant modulations require sophisticated theoretical understanding and agile execution.
