- Establishes C major via an extended Dm11 before an early pivot to C minor (Cm11) and subsequent modulations.
- Features a rapid and unexpected
ii-Vprogression (Bbm7-Eb7) to Ab major, demonstrating sophisticated harmonic movement. - Incorporates a distinct D pedal point section (
G/D, Am7/D, Bb0/D, Bm7/D), showcasing advanced upper-structure voicings and chromatic bass movement. - Employs modal interchange and chromaticism throughout, moving between major, minor, and diminished sonorities.
Improvisation Focus: Navigating modal interchange and target key scales during rapid modulations.
Difficulty Rating: 4 (Advanced). The frequent modulations, pedal point section with unusual voicings, and implied harmonic complexity require a deep understanding of jazz harmony.
