Exploration of musical possibilities within the harmonic structure of the theme. Does not depend on motifs. Does not have a constant base note for each bar. Theme is in 2 parts, the second of which I do not quite use. The recitative is not a variation and is meant to be a break. The 2nd part of it is wrong, will change. There is a semi-failed variation that can only be played by 2 hands. I do not know how to adapt it for 1 hand only. I am currently out of ideas for another variation.
