For no real, apparent reason, I chose “26-2”, which is itself Coltrane's "Descending Maj 3rds Cycle" adaptation of Charlie Parker's “Confirmation”
Rather than try to completely do my own thing with the melody, I chose to stick with 'Trane's original melodic rhythm and stay as true as possible to his original melodic shapes, adapting them to the change in direction of the Maj 3rds harmonic cycle.
