- Employs the “Three-Tonic System” (Coltrane Changes) superimposed onto the “How High the Moon” framework, cycling through G, Eb, and B major tonalities.
- Utilizes symmetrical root movements where each tonic is preceded by its dominant (V7) located a major third away from the previous key.
- Integrates standard ii-V-I cadences (e.g., Gm7–C7–Fmaj7) to bridge the complex major-third cycles back to the primary tonal center.
Improvisation Focus The “Three-Tonic System.” Success requires mastering “digital patterns” (1-2-3-5) and fluid voice-leading across keys separated by major thirds at high velocity.
Difficulty Rating 5/5. The combination of rapid harmonic rhythm, non-diatonic modulations, and the fast tempo typical of Coltrane’s “sheets of sound” era represents an apex challenge for improvisers.
