Harmonic Highlights:
- The piece frequently establishes
Ebmaj7as a tonic, creating a major resolution within the stated Eb minor key center, suggesting a strong Picardy third or modal interchange. - Successive ii-V progressions drive the harmony, briefly tonicizing keys like Db (bIII), Gb (bVI), and most notably E (bII) in the bridge.
- The bridge features a striking
F#m7-B7(ii-V of E) progression, introducing a distant, chromatic modulation that temporarily moves far from the Eb home key before resolving. - Harmonic movement is largely defined by chains of ii-V cadences, requiring constant adaptation to new temporary tonicizations.
Improvisation Focus: Chord-scale navigation over rapid ii-V progressions.
Difficulty Rating: 4 (Advanced) - The frequent and often remote modulations, particularly the F#m7-B7, demand a high level of harmonic sophistication and agility.
