I would suggest that the challenge be repeated in the future with themes from other composers in YC. I think everyone will benefit from seeing how their themes are developed by other composers with their own particular compositional philosophies, skill, and inspiration, as well as be challenged to broaden their scope of composition from the musical (as opposed to inert verbal) insights received. I guess that the participants would also benefit from the challenge (it is up to the participants to speak here). It is also a way of creating musical/compositional interaction among the members of YC (in addition to only verbal). By the way, the challenge is still going on; and I think I will receive further insights with each new contribution to it.
