Harmonic Highlights
- Prominent use of tritone substitutions, such as
B7acting asbII7resolving toBbmaj7(IV), creating chromatic voice leading. - Sequential ii-V progressions, like
Am7-D7(ii-V of Gm) leading toGm7-C7(ii-V of F), offering temporary tonicizations. - A sophisticated
ii-Vin Ab major (Fm7-Bbm7) followed by a highly altered dominantG7b9#11resolving toC7(V of F).
Improvisation Focus Altered scale (Super Locrian).
Difficulty Rating 4 (Intermediate-Advanced). It demands a strong understanding of altered dominants, tritone substitutions, and sophisticated harmonic pathways.
