Harmonic Highlights:
- The Em7-A7 progression introduces a striking half-step modulation, functioning as a ii-V leading to D major, departing from the home key of Db.
- Frequent non-diatonic ii-V cycles, such as Abm7-Db7 (to Gb) and Gm7-C7 (to F), create temporary tonicizations in distant keys.
- Consistent return to Dbmaj7 grounds the harmony, often culminating in the modern, lyrical sound of a Dbmaj7#11 voicing.
Improvisation Focus: Navigating rapid, often non-diatonic ii-V progressions through precise chord tone targeting and appropriate scale shifts.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent and sometimes unexpected modulations demand a sophisticated harmonic ear and agility from improvisers.
