Harmonic Highlights

  • Prominent use of the bVImaj7#11 (Fmaj7#11), introducing a characteristic non-diatonic color and Lydian sound within the A major tonality.
  • Frequent tonicization and modulation to the mediant major (C#maj7) and relative minor (F#m7) through strong ii-V-I progressions and altered dominants (e.g., G#7#9, C#7b9).
  • Sophisticated extensions of ii-V progressions, often employing secondary dominants (e.g., C#m7 F#7b9 leading to Bm7) and chromatic alterations (b9, #9) for tension and resolution.

Improvisation Focus Emphasize precise chord-scale application and arpeggios over rapidly shifting harmonic centers.

Difficulty Rating 4 (Advanced Intermediate) - The frequent modulations, non-diatonic chords, and altered dominant qualities require a solid understanding of advanced harmony and fluent scale/arpeggio application.
