Harmonic Highlights

  • Secondary Dominant (III7): The E7 chord functions as a chromatic lift, creating a “sunny” tension that resolves to either the IV (Fmaj7) or the relative minor (Am7).
  • Chromatic Bass Motion: The progression C6 – E7/G# – Am7 utilizes a G–G#–A ascending line, providing a smooth melodic bridge between the tonic and submediant.
  • Subdominant Modulation: The bridge pivots to F major using a ii-V7 (Gm7–C7), followed by a secondary dominant (D7) to return to the primary key via G7.

Improvisation Focus Chord-tone targeting over secondary dominants (E7, D7, C7) within the C major scale framework.

Difficulty Rating 2/5: The AABA structure and clear functional harmony make it an ideal entry point for learning secondary dominants and basic modulations.
