Departing from a distinction between music creation and sound or pre-established methods of form and sound manipulation,the paper discusses the use of some typical procedures in computer aided composition. Critique of common-sense procedures intend to show that musical creativity may be threatened and risked in the name of a community's immediate acceptance of a what is considered to be of musical value. Thought and practice of language crossings ground musical works and sorts of musical listening much earlier then the use of such accepted procedures.
