Harmonic Highlights:
- Prominent use of the
Ebm7(iv minor) chord, creating a distinctive melancholic modal interchange from the parallel minor. - Sophisticated chromatic voice leading, notably the
E7(bVI7) toEb7(V7), functioning as an altered dominant or tritone substitution leading to the true dominant. - Inclusion of a
Gb7(bVII7) backdoor dominant, providing a smooth, blues-inflected resolution to the tonicAbmaj7. - Frequent deployment of altered dominants like
Eb7#5and secondary dominants (Bb7) to add harmonic tension and color.
Improvisation Focus: Modal Interchange.
Difficulty Rating: 4 (Advanced Intermediate). It features non-diatonic chords like the iv minor and backdoor dominant, alongside altered dominants and chromatic substitutions, requiring a flexible harmonic approach.
