Harmonic Highlights

  • Employs a classic I - #io7 - ii - V turnaround (Cmaj7 - C#o7 - Dm7 - G7) in the A sections, using the diminished chord for chromatic root movement.
  • Features a chromatic ascending sequence (Dm7 - Ebo7 - Em7) where the #iio7 functions as a passing chord to the iii.
  • Incorporates the Bb7#11 as a bVII dominant chord, providing a Lydian Dominant color that often leads to the VI7 (A7) via chromatic voice-leading.
  • Utilizes a series of secondary dominants (A7 to D7 to G7) to create a strong cycle-of-fifths pull back to the tonic.

Improvisation Focus C Major Bebop scale and chord-tone targeting to navigate the frequent chromatic passing chords and secondary dominants.

Difficulty Rating 3/5. While the key is simple, the fast harmonic rhythm and non-diatonic passing chords require precise guide-tone navigation.
