Harmonic Highlights
- Prominent chromatic II-V-I sequences (e.g.,
Bbm7-Eb7-Abmaj7-Db7) create temporary modulations to distantly related keys, hinting at ‘Coltrane Changes’ aesthetics. - Regular use of secondary dominants (
D7,D7b9) with both standard (D7b9-Gm7) and altered resolutions (D7-Bbmaj7). - The recurring
B07(B diminished 7) adds chromatic tension, often functioning as a passing or substitute dominant.
Improvisation Focus Altered Dominant Scales and arpeggios over temporary tonicizations.
Difficulty Rating 4 (Advanced). The rapid chromatic modulations and varied dominant resolutions demand sophisticated harmonic awareness.
