Harmonic Highlights

  • Employs chromatic stepwise motion (F - F#ยฐ7 - Gm7) using a #I diminished chord to bridge the tonic and the supertonic.
  • Incorporates secondary dominants with altered extensions, such as A7b13 (V/vi) and D7b13 (V/ii), to facilitate smooth voice leading and internal tension.
  • Utilizes a Gm6 to G#ยฐ7 transition as a diminished approach to the I chord in first inversion (Fmaj7/A), creating a rising bass line.
  • Features minor ii-V sequences (Am7b5 - D7b13) to target the ii chord (Gm7), adding sophisticated minor-key coloration to a diatonic major framework.

Improvisation Focus Guide Tone Mapping is essential to navigate the frequent chromatic passing chords and altered dominant resolutions effectively.

Difficulty Rating 3/5: The melody is deceptively simple, but the harmonic structure requires precise navigation of diminished substitutions and altered secondary dominants.
