  • Harmonic Highlights:

    • Frequent use of II-V-I progressions (Am7-D7 to Gmaj7) firmly establishes and reiterates the tonic.
    • Tonicization of the subdominant (IV) occurs with the Dm7-G7 leading to Cmaj7.
    • A secondary dominant progression (Bm7b5-E7 to Am7) temporarily targets the supertonic.
    • An interesting Am7b5-D7 leading to Gmaj7 suggests a minor iiø7-V7 resolving deceptively to a major tonic.
  • Improvisation Focus: Functional Harmony and Chord Tones.

  • Difficulty Rating: 3 (Intermediate) - The tune features standard jazz changes with clear II-V-I patterns and common tonicizations, but includes a few less common resolutions requiring careful navigation.
