  • Harmonic Highlights

    • Dominant use of the II-V-I progression (Am7-D7-Gmaj7) firmly establishing G major.
    • Brief tonicization of C major via the Dm7-G7 (ii-V) sequence.
    • Inclusion of non-diatonic chords (Cm7, F7) which create a momentary chromatic departure before returning to the main II-V-I.
  • Improvisation Focus G Major Scale (including its related modes).

  • Difficulty Rating 3 (Intermediate). The harmonic framework is built on common II-V-I progressions, but the tempo and occasional non-diatonic chords require attentive navigation.
