- The use of F7 (VI7) as a secondary dominant to Bbm7 (ii) establishes a characteristic Monk-esque dominant cycle.
- A classic Imaj7 - I7 - IVmaj7 progression (Abmaj7 - Ab7 - Dbmaj7) incorporates the I7 as a dominant function.
- Abrupt modulations to new key centers are prominent, exemplified by the Dm7-G7 (ii-V of C major) and Gm7b5-C7 (ii-V of F minor) sequences.
- Chromaticism is vital, with chords like D07 and F7#11 introducing significant tension and unexpected resolutions.
Improvisation Focus: Navigating transient modulations with precise chord-scale application.
Difficulty Rating: 5 (Advanced). The numerous, abrupt key center shifts and sophisticated dominant alterations demand advanced harmonic understanding and execution.
