Pietro Antonio Locatelli (1695–1764) was an Italian composer and violinist. Locatelli was born in Bergamo in Italy on 3rd September 1695. A child prodigy on the violin, he was sent to study in Rome under the direction of Arcangelo Corelli. Little is known of his subsequent activities except that he finally settled in Amsterdam in 1729, where he died on 30th March 1764. Locatelli was a virtuoso violinist, said never to have played a wrong note -- except once, when his little finger slipped and got stuck in the bridge of his instrument.
