Harmonic Highlights

  • Employs a prominent secondary ii-V (F#m7b5 โ€“ B7b9) to tonicize the mediant (Em7), creating a brief shift to E minor tonality.
  • Uses a Gm7 โ€“ C7 sequence to tonicize the IV chord (F major), a hallmark of Gershwin-era subdominant movement.
  • Features chromatic tension via the C#7b13 chord, serving as a substitute dominant or chromatic connector to lead back into the F#m7b5.
  • Relies on standard I-vi-ii-V turnarounds (Cmaj7 โ€“ Am7 โ€“ Dm7 โ€“ G7) to reinforce the C major tonic between secondary modulations.

Improvisation Focus Targeted chord-tone soloing to navigate frequent secondary ii-V-I cycles.

Difficulty Rating 3/5; the harmonic rhythm is steady, but the frequent secondary dominants and minor ii-V-I sequences require precise melodic targeting beyond the home scale.
