A group of 10- and 11-year-olds giggle as professional cellist Frederic Rosselet flexes his wrist as if he's made of rubber. "Really flexible in your wrist," he tells the students. "It's your arm basically that does the work."
The cello students at Downer Elementary School in San Pablo, Calif., drag their bows across their cello's strings, following Rosselet's wrist-shaking lead.
Screeeech. It needs work.
"Guys, wanna try that again? 'Forte' means?"
"Loud!" the students reply.
