Harmonic Highlights

  • Uses a chromatic ii-V (Cm7–F7) to approach the iii chord (Bm7), a characteristic “cool jazz” subversion of standard diatonic functional harmony.
  • Employs extended circle-of-fifths sequences (Bm7–E7–Am7–D7) that provide the foundational “walking” momentum typical of Mulligan’s style.
  • The bridge features a temporary modulation toward the mediant (B minor) via a ii-V (C#m7b5–F#7b9), requiring precise navigation of the minor tonal center.
  • Incorporates secondary dominants like G7b9 to create melodic tension that resolves into the subdominant or related ii-V patterns.

Improvisation Focus G Major Bebop scale and fluid guide-tone voice leading through rapid ii-V-I cycles.

Difficulty Rating 3/5: The moderate tempo allows for melodic development, but the frequent ii-V turnarounds and bridge modulations require disciplined harmonic awareness.
