Harmonic Highlights:
- Establishes Bb major with a foundational I-vi-ii-V progression (Bbmaj7, Gm7, Cm7, F7) before significant departure.
- Features rapid modulations through a series of ii-V progressions often related by descending major thirds or chromatic steps (e.g., Bm7-E7, Bbm7-Eb7, Am7-D7, Abm7-Db7), reminiscent of “Giant Steps” changes.
- Employs chains of dominant chords and secondary dominants, leading to temporary tonal centers that shift every one or two bars (e.g., Fm7-Bb7-Eb7, Ab7).
- High harmonic rhythm demanding precise navigation through complex, non-diatonic chord changes.
Improvisation Focus: Arpeggio outlining for each specific chord.
Difficulty Rating: 5 (Advanced). The tune features extremely fast harmonic rhythm and constantly shifting tonal centers requiring advanced melodic and harmonic understanding.
