Harmonic Highlights:
- Prominent use of secondary dominants (G7b9, F7) and a vii°7 (B07) to create strong minor-key functional harmony.
- A significant tonicization of D major (V of G minor) via an Em7-A7-Dmaj7 ii-V-I, introducing a contrasting bright quality.
- Features a complex, distant modulation to Gb major through an Abm7-Db7-Gbmaj7 ii-V-I progression, showcasing sophisticated harmonic movement.
- Incorporates altered dominants like G7b9 and Eb7#11, adding chromatic tension and color.
Improvisation Focus: Chord-Scale theory applied to transient modulations, precisely outlining each new tonal center.
Difficulty Rating: 4 (Advanced). The rapid and distant modulations require a sophisticated understanding of multiple key centers and altered scales.
