To this end, music is a necessary, life-enhancing experience which should be nurtured in all individuals, not only in those gifted with musical aptitude. Music is an invariant. It has been present in all cultures, at all times, and throughout the known historical development of the human species, facilitating emotional, physical, and social expression. Music satisfies the human need for aesthetic enjoyment, provides for communication of cultural ideals, integrates, and enculturates. It serves as both a reflection of, and a catalyst for sociological and technological growth.
Music is both art and science.
As an art, it manifests itself as the result of a creative process and of performance skill, in both cases requiring practice and refinement. As a science, its manipulation is subject both to physical laws and to theoretical structure. Innovations of musical performance result from and contribute to broader innovations. Musical function can be as much utilitarian as emotional. Music can fulfill extra-musical objectives in influencing human behavior.
