Harmonic Highlights:
- Employs diatonic II-V-I progressions (Gm7-C7-Fmaj7) and secondary dominants (D7 as V7/ii) to articulate the primary tonality.
- Features prominent, abrupt modulations to distantly related keys, specifically Gb major (bII) via Abm7-Db7 and D major (bIII) via Em7-A7.
- The recurrent Abm7-Db7-Gbmaj7 sequence acts as a bII-V-I progression, showcasing principles of tritone substitution and sudden tonal shifts.
Improvisation Focus: Navigating rapid key center changes and their corresponding modal applications.
Difficulty Rating: 4 (Advanced Intermediate). The frequent and often abrupt modulations to distantly related keys demand sophisticated harmonic understanding and improvisational agility.
