I will give you your choice of either a piano(or organ) prelude and fugue using full proper contrapuntal technique, or a short concerto for chamber orchestra for the whole thing, featuring your choice of classical instrument for the solo and cadenza(Yes, the Theremin is a classical instrument BTW) Of course, you will also receive all publishing rights to said works, and your name will be on the dedication.
What do you say?
:-D
