The Chinese pianist Liu Chi Kung was imprisoned for seven years during the Cultural Revolution, during which time he had no access to a piano. When he returned to giving concerts again after he was released, his playing was better than ever. Asked how this was possible since he had not practice for seven years, he replied: ''I did practice, every day. I rehearsed every piece I had ever played, note by note, in my mind.''
