A hallmark of the philosophy of Confucius is his emphasis on tradition and study. He disparages those who have faith in natural understanding or intuition and argues for long and careful study. Study, for Confucius, means finding a good teacher, who is familiar with the ways of the past and the practices of the ancients, imitating his words and deeds. The result is a heavy scheme of obligations and intricate duties throughout all of one's many social roles. Confucius is said to have sung his sayings and accompanied himself on a 'qin' (a kind of zither). According to Confucius, musical training is the most effective method for molding the moral character of man and keeping society in order. He said: "Let a man be stimulated by poetry, established by the rules of propriety, perfected by music."
