Harmonic Highlights
- Prominent use of classic ii-V-I progressions in Ab major, establishing the core tonality.
- Modulation to the subdominant (Db major) via Ebm7-Ab7-Dbmaj7, expanding harmonic movement.
- Characteristic Bebop bVII7 chord (Gb7#11) resolving to the tonic (Abmaj7), adding unique color.
- Frequent application of secondary dominants (e.g., F7b9 as V/ii, Bb7#11 as V/V), creating strong forward motion.
Improvisation Focus Altered Dominant Scale
Difficulty Rating 4 (Advanced). The frequent altered dominant chords and the bVII7 resolution demand sophisticated scale choices and harmonic understanding.
