Harmonic Highlights
- Frequent use of Ebm6 as the tonic, establishing a strong minor tonality despite an overall Eb major key center.
- Chromatic dominants like B7 (bVI7) and Db7 (bVII7) provide color, often functioning as deceptive or backdoor dominants.
- The ii-V-i progression (Bbm7b5, Eb7b9, Abm6) briefly modulates to Ab minor, adding a temporary harmonic center.
- Tritone substitution is utilized, exemplified by E9 (bII7) resolving directly to the Ebm6 tonic.
Improvisation Focus Melodic Minor Modes.
Difficulty Rating 4. The blend of minor tonality, chromatic dominants, and temporary modulations demands advanced harmonic understanding.
