Harmonic Highlights
- Prominent use of altered dominant chords (e.g., B7#5, A7b13) generating heightened chromatic tension and leading tones.
- Frequent secondary dominant function (A7 to Dm) and temporary tonicizations, like the ii-V-I in F major (Gm7-C7-F7).
- Strategic inclusion of chromatic diminished chords (F#07) and tritone substitutions (Ab7 for D7) adding harmonic complexity.
Improvisation Focus: Navigating altered dominant scales (e.g., Altered Scale/Super Locrian) over V7 chords with extensions.
Difficulty Rating: 4 (Advanced Intermediate). The prevalence of altered dominants, chromatic passing chords, and varied temporary tonicizations requires a developed harmonic ear and theoretical knowledge.
