The Wrong Violin
Nicolo Paganini (1782-1840), one of the greastest violinists of all time, was about to perform before a sold-out opera house. He walked out on to a huge ovation and felt that something was terribly wrong.
Suddenly he realized that he had someone else's violin in his hands. Horrifed, but knowing that he had no other choice he began. That day, he gave the performance of his life.
After the concert, Paganini reflected to a fellow musician, "Today, I learned the most important lesson of my career. Before today, I thought music was in the violin. Today, I learned that the music was in me."
