Harmonic Highlights
- Features extensive chromatic dominant chord movement, such as
G7 - Gb7 - F7andE7 - Eb7, creating continuous tension and resolution. - Employs tritone substitutions (
Gb7for an impliedC7,Eb7forA7) to alter expected dominant resolutions and add harmonic color. - Frequent use of minor ii-V-i progressions (e.g.,
Bm7-E7b9-Am7) leads to temporary tonicizations away from the C minor key center. - Incorporates prominent altered dominants, like
E7b9, for enhanced tension and sophisticated voice leading into target chords.
Improvisation Focus Mastery of altered dominant scales (Mixolydian b9b13, Altered Scale) to navigate the frequent dominant shifts.
Difficulty Rating 4 (Advanced Intermediate) – The continuous chromatic movement, numerous temporary tonicizations, and complex dominant alterations demand a sophisticated harmonic understanding.
