Who composed a work for piano solo that bears the instruction to repeat 840 times? Can you name the work? <Ok, so maybe some of these are too hard. However, I'm also doing this to share some piano literature highlights/gems/oddities for the benefit of all. I expect to be the only person on PS that actually participated in its performance. I've mentioned this work before in another unrelated thread.>
I'm sure I read about this recently somewhere, and that it involved people having to play it in shifts because otherwise they would at worst suffer from sleep deprivation, or at best need to be sitting on a commode. It's Erik Satie. I didn't immediately recall the name of the work, but when Google duly obliged, I remembered having seen it in that context.
