Harmonic Highlights

  • Sequential I-IV movements side-slip chromatically (D6-G6 to Eb6-Ab6), creating brief, non-diatonic excursions that challenge the established F major tonic.
  • Reliance on major 6th voicings instead of major 7ths maintains a vintage swing character, providing a more “consonant” yet colorful harmonic palette.
  • The progression utilizes rapid cycles of dominant-to-tonic resolutions (F7-Bb6, G7-C6) to navigate through multiple key centers within a short timeframe.

Improvisation Focus Rapid transposition of major pentatonic scales and chord-tone targeting to outline the shifting tonal centers.

Difficulty Rating 3/5 - While the chord qualities are basic, the brisk harmonic rhythm and constant modulation through distant keys require significant mental agility.
