 The Records of Ritual, the Analects, and numerous Han collections portray Confucius as being deeply concerned with the proper performance of ritual and music. In such works, the description of the attitudes and affect of the performer became the foundation of a ritual psychology in which proper performance was key to reforming desires and beginning to develop moral dispositions. Confucius sought to preserve the Zhou ritual system, and theorized about how ritual and music inculcated social roles, limited desires and transformed character.
