Menuhin lived to play
Menuhin didn't just play the violin. Rather he seemed to regard music as a kind of prayer made audible, and mellifluous. Nothing in the world was so natural, or so pleasurable. Nothing was more indispensable.
His own abilities were deeply paradoxical: there was his immense faith in his musical gift; but he had a most beguiling sense of his own uncertainties and flaws.
He was against the notion that says you cannot make music unless you make it perfectly. He took the view that it is music that perfects the artist. Not the other way around. Music for Menuhin was not about success, it was a life-support system.
