  • Harmonic Highlights:

    • Prominent use of the IV chord (Cmaj7/C6) as a strong landing point, often preceded by a v-I progression (Dm7-G7) creating a tonicization of the subdominant.
    • Inclusion of the secondary dominant B7 (V/vi) resolving to Em7 (vi), and the Eb07 (bVIø7), adding chromatic interest and tension.
    • The Dm, Dm/maj7, Dm7 sequence over the v chord provides internal voice leading and nuanced harmonic color.
    • A D#0 chord (possibly viiø7/vi or chromatic passing diminished) introduces an altered sound before Cmaj7/E.
  • Improvisation Focus: Navigating the frequent temporary tonicizations of C major (IV), requiring a flexible approach between G major and C major-centric scales.

  • Difficulty Rating: 3 - Intermediate: Requires adept handling of standard jazz voicings, secondary dominants, diminished chords, and temporary modulations to the subdominant.
