At twelve years old he became completely blind, when he was hit on the head while playing football. Bocelli does his best to ignore his blindness. He says, “Italy‘s traditions, as well as my parents, have taught me never to accept life’s difficulties in a passive （被动的） way, but rather to draw strength（力量）from them.

Bocelli showed musical ability early in life. As a young boy, Bocelli showed a great passion for music. His mother has said that music was the only thing that would comfort him. At the age of six, he started piano lessons, and later, also learned to play the saxophone, guitar and drums and so on. He won his first singing competition when he was twelve.
