"It wasn't enough to be a great soloist - Menuhin wanted to be a great leader in music. He wanted to teach, open a music school and conduct the world's best musical groups. Menuhin knew that if he wanted to teach a class or lead an orchestra, he couldn't rest on his past achievements. He needed to understand the steps he'd taken to play so well."
