- The Bbm7-Eb7 progression functions as a “backdoor” ii-V, resolving deceptively to Fmaj7.
- Frequent use of non-diatonic ii-V cycles (e.g., Abm7-Db7) and secondary dominants (Am7-D7) shifting temporary tonal centers.
- Sudden chromatic alterations, such as the appearance of Dmaj7 (bVImaj7), introduce striking harmonic contrast.
Improvisation Focus: Chord-Scale Approach outlining specific arpeggios and modes for each chord.
Difficulty Rating: 5 (Advanced) due to the frequent, rapid modulations and non-diatonic progressions requiring precise melodic navigation.
