Harmonic Highlights:
- Extensive use of secondary dominants (e.g., G7-Cm7, C7-F7) and II-V progressions, often leading to temporary tonicizations.
- Chromatic dominant alterations like Ab7#5 and the D07 passing diminished, adding tension and color.
- Striking, abrupt modulations demonstrated by the F#m7-B7-Bbmaj7 sequence, shifting the tonal center unpredictably.
- Incorporates half-diminished chords (Cm7b5) within complex progressions, demanding precise navigation.
Improvisation Focus: Navigating rapid, non-diatonic II-V-I cycles and highly altered dominant chords.
Difficulty Rating: 5 (Advanced). The tune features fast-moving, remote modulations and dense chromatic harmony, requiring sophisticated harmonic understanding.
