Sydney Eddison recounts [a story] of the violinist Itzhak Perlman, who as a boy was struck with polio and who as a man must walk with the aid of leg braces and crutches:
At a concert on the night of November 18, 1995, at Avery Fisher Hall in New York City, one of the strings of his violin suddenly snapped during the performance. Stunned, the audience held their collective breath, expecting Perlman to stop and leave the stage. Instead, he paused, then continued playing — adjusting, creating, compensating as he went along, and when he put down his bow at the end of the concert, a mighty roar of applause filled the hall. When it had died down, he spoke to the audience: “You know, sometimes it is the artist’s task to find out how much music you can still make with what you have left.”+ + +
