Harmonic Highlights
- Employs unexpected chromatic mediant relationships, such as
Ebmaj7toEmaj7toBmaj7, creating abrupt key shifts and tonal ambiguity. - Features non-functional dominant resolutions like
A13b9toGbmaj7, introducing remote tonal centers and tritone substitution concepts. - Frequent use of altered dominants (
Bb7alt,D7b9) and suspended chords (F7sus,Bb7sus) to build tension and delay definitive resolution. - Incorporates Lydian colorations (
Ebmaj7#11) and chromatic approaches (Emaj7/Eb) within established major sections, adding distinctive modal flavor.
Improvisation Focus Navigating localized chord-scales and arpeggios through rapid, non-functional harmonic progressions.
Difficulty Rating 5 (Advanced) - Its pervasive chromaticism, sudden modulations, and non-diatonic progressions require a sophisticated understanding of harmony and precise execution.
