Harmonic Highlights
- Persistent use of a
bIIIm7 (Ebm7) -> IV7#9 (E7#9)vamp, establishing a distinctive modal-blues foundation outside strict B major diatonicism. - Frequent chromatic dominant chord shifts, notably
Ab13 -> A13andB13 -> C13, adding unexpected tension and melodic possibilities. - Strategic tonicizations, such as
Ebm7 -> Ab13(ii-V in Db) andBb7b13 -> Ebm7(V-i in Ebm), exploring parallel minor and related keys. - Integration of a “tonic dominant” (
B13) which imbues the tonic chord with a driving, blues-infused character common in soul jazz.
Improvisation Focus Blues scale, particularly over the dominant 7#9 chords.
Difficulty Rating 4/5: Requires navigating frequent non-diatonic chord progressions, chromatic dominant shifts, and tonicizations outside the primary key center.
