Harmonic Highlights:
- The opening
Ebm7b5 - Ab7b9 - Dbmaj7immediately establishes a parallel major tonality (C#maj7) via a iiø7-V7, surprising given the stated C# minor key center. - Extensive use of chromatic descending dominants and tritone substitutions, exemplified by the
Gb7, F7, Bb7, A7, Ab7, G7sequence, drives rapid, often unresolved, harmonic motion. - Modulations to distant key centers, such as the
F#m7 - B7 - Emaj7progression, showcase complex reharmonization and temporary tonicizations.
Improvisation Focus: Arpeggio Superimposition.
Difficulty Rating: 5 (Advanced). The rapid, often non-diatonic modulations and complex chord progressions demand sophisticated harmonic understanding and agility.
