The form of a folk song as heard at any one time, however, is likely to have been very much affected by the entire community because of its life in oral tradition. Once introduced, a song could be easily dropped from the repertory. More likely, however, as it was passed from parents to children and to friends and associates and coworkers, it would be changed. Numerous influences acted on a song, including creativity, forgetfulness, previously learned songs, and stylistic expectations. As a result, it might become shorter or more like new styles of popular or church music, for example. Any new song would be likely to undergo this process of communal re-creation. An important characteristic of a song or piece in traditional folk culture is, thus, its dependence on acceptance by a community—that is, by a village, nation, or family—and its tendency to change as it is passed from one individual to another and performed.
