Harmonic Highlights:
- Extensive modal interchange featuring Bbm9 (bVII) and Ebm7 (bIII from Bb minor) for strong minor key coloration against the Bb major tonic.
- Chromatic mediant progressions, notably Gbmaj7 (bVI) moving to Bbmaj7#5 (Iaug), creating an altered and expansive sound.
- Abrupt chromatic shifts, such as Bbmaj7#5 to Bmaj7#11, introduce harmonic ambiguity and tension without clear functional resolution.
- Sustained use of Gm11/Gm9 (vi) acts as a recurring, richly textured modal anchor, contrasting with the surrounding chromaticism.
Improvisation Focus: Chromaticism.
Difficulty Rating: 5 (Advanced). Complex modal interchange, sudden chromatic shifts, and non-functional progressions demand sophisticated harmonic adaptability for improvisation.
