Harmonic Highlights:

  • Establishes the C major key center through repeated ii-V-I progressions (Dm7-G7-Cmaj7).
  • Utilizes secondary dominants like A7 (V7/ii) to create stronger resolutions to target chords.
  • Features a chromatic passing diminished chord, Eb07, acting as a V7b9 substitute (A7b9) leading to Dm7.
  • Includes F#m7b5 (iiø7/iii), implying a brief tonicization towards the mediant (Em).

Improvisation Focus: Navigating ii-V-I cycles and secondary dominant alterations.

Difficulty Rating: 3 (Intermediate). The tune combines fundamental ii-V-I progressions with crucial secondary dominants and chromatic passing chords requiring specific harmonic awareness.
