Jackie, going slightly off track, this "play-space" that you mention above is apparently hyper active in the night while muscians sleep. I've often heard of their (and my own) experience of working out extremely difficult technical passages during the day, quitting, then after waking, to be able to play the passages near perfectly. I would love to know what goes on in the brain during sleep that enables this phenomenon. And is it just limited to music? The remarkable thing about the "play-space" in sleep is there is a physical leap, a muscular one, that occurs so that what was unplayable has miraculously become very playable.

Thank goodness for the power of sleep.
