Harmonic Highlights:

  • Prominent use of ii-V-I progressions, notably Am7-D7 resolving to Gmaj7 or G6.
  • Frequent deployment of the II7 chord (A7) often functioning as V7/V, creating strong dominant function towards the D7.
  • A chromatic diminished chord (Bb07) introduces tension, acting as a passing diminished or vii°7/ii before the Am7-D7.

Improvisation Focus: G Major scale and its diatonic modes, with a strong emphasis on Mixolydian over dominant 7th chords.

Difficulty Rating: 3 (Intermediate) - The tune features standard ii-V-I progressions alongside common chromatic alterations like the II7 and passing diminished chords, requiring thoughtful melodic navigation.
