...for me, anyway.
I had my younger violin group the other day, who are all in the seven-ish age range. One of their favorite activities at the moment is to play pieces while lying down. Last group, the conversation went something like this (and it doesn't really matter who's speaking, just picture a swarm of four seven-year-olds. Oh my, can they swarm):
"Next time, can we play standing on our heads?"
Me: That doesn't sound particularly safe...
"Someone could do that though if they were a really good acrobat."
"A really good acrobat could play violin on a tightrope!"
"On a bicycle on a tightrope!"
"There could be a horse under the tightrope and they could jump off the bicycle and land on the horse and keep playing the violin!"
I hereby disavow any and all responsibility for any violin-tightrope-bicycle-horse-related incidents. Ever.
