Harmonic Highlights:
- Prominent modal interchange, notably the use of
Gmaj7(bVIImaj7) andDm7(IVm7), coloring the A major tonic with parallel minor and Lydian b7 influences. - Frequent chromatic passing chords like
Abm6andFm7, creating unexpected shifts and intricate voice leading. - Application of tritone substitution (
Bb9) and secondary dominants (F#7b9,A7) for sophisticated harmonic drive and temporary resolutions.
Improvisation Focus: Scale adaptation for shifting modal centers and chromatic alterations.
Difficulty Rating: 5 (Advanced). The rapid, non-diatonic chord changes and frequent modal mixture require a deep harmonic understanding and agile improvisational vocabulary.
