Harmonic Highlights:
- The
Db7#11(bVII7) resolving toFm7(ii) rather than the tonic (Ebmaj7) offers a sophisticated backdoor dominant variation. - Intricate voice leading is evident in the
A07(vii°7 of Bb) resolving toEb6/Bb, creating a smooth, sustained pull towards the tonic. - Standard secondary dominants, notably
Eb7(V7/IV) andC7b9(V7/ii), are used to articulate and expand the core ii-V-I harmonic movement.
Improvisation Focus: Eb Major scale and its diatonic modes (Mixolydian for dominants, Dorian for minors).
Difficulty Rating: 3 (Intermediate). The interplay of secondary dominants, backdoor variations, and diminished chord resolutions requires attentive harmonic understanding.
