why? why would you want to see someone 'crash and burn.' you are pianists. you should be ashamed of yourselves! you would enjoy that quiet senseless moment where one simply starts over again - and laughs - or whatever horowitz did that one time in his entire career where something or other didn't start right. after so many years of all these pianists performing - i don't think it would really phase them. in fact -they probably just move tot he next spot and nobody but pianists would know they missed one,two, or three notes. you have to remember - these guys/girls have made careers already.
more likely that amateurs would crash and burn much worse.
