Harmonic Highlights:

  • Prominent modal interchange, notably the use of Gmaj7 (bVIImaj7) and Dm7 (IVm7), coloring the A major tonic with parallel minor and Lydian b7 influences.
  • Frequent chromatic passing chords like Abm6 and Fm7, 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.
