Harmonic Highlights

  • The opening bVIImaj7#11 (Gbmaj7) to vi7 (Fm7) progression creates a non-functional, Lydian-inflected atmosphere that avoids immediate tonic resolution.
  • A sudden shift to E major via a ii-V-I (F#m7–B7–Emaj7) introduces a remote tonal center (bVI relative to the home key), necessitating quick harmonic pivoting.
  • The turnaround employs a rising stepwise bass line (C7/D to C7/E) to build tension before resolving to the relative minor (Fm7).

Improvisation Focus Navigating rapid modulations between distantly related keys (Ab major and E major) while maintaining the 3/4 waltz feel.

Difficulty Rating 3.5/5. The moderate tempo is accessible, but the constant shifting between unrelated tonal centers and the non-diatonic Lydian colors require sophisticated harmonic navigation.
