Harmonic Highlights
- Strategic deployment of tritone substitutions (e.g., Ab7 preceding D7#9) to introduce chromatic tension.
- A blues-infused dominant cycle (G7 - C7#9 - F7) frequently utilizes #9 alterations, driving the progression.
- The V7 chord (D7#9) consistently features a #9, reinforcing a hard-bop minor tonality.
- An opening minor progression (Gm7-Em7b5-Eb7-Dm7) demonstrates non-diatonic or passing chord movement beyond typical functional harmony.
Improvisation Focus Altered Scale applications over dominant chords.
Difficulty Rating 4 - The frequent use of altered dominants, tritone substitutions, and non-diatonic minor progressions demands sophisticated harmonic understanding and navigation.
