Initiates go through a severe education in ritual behavior, ritual language, music, and dance, all for serving their particular deity. In effect, this liturgical behavior results from a deep sociocultural conditioning, of which the performance of sacred songs and dances represents an integral part. The relationship of music and spirit possession also results from this conditioning; that is, initiates are taught the meaning of certain songs within the mythology of their specific orixá [deity, saint] and the corresponding expected behaviorial response. It is therefore the association of such sacred ritual songs and corresponding accompanimental rhythms with their respective god that triggers the trance behavior, not necessarily fast and loud drumming as is usually believed.)
