Recent innovations in musical instrument design are not simply a response to the needs of musicians, writes Paul Theberge; they also have become "a driving force with which musicians must contend." He argues that digital synthesizers, samplers, and sequencers in studio production and in the home have caused musicians to rely increasingly on manufacturers for both the instruments themselves as well as the very sounds and musical patterns that they use to make music. <br><br>Musical practices have thus become allied with a new type of consumer practice that is altogether different from earlier relationships between musicians and their instruments as a means of production. Theberge places these developments within a broad social and historical perspective that examines the development of the musical instrument industry, particularly the piano industry, the economic and cultural role of musicians' magazines and computer networks, and the fundamental relationships between musical concepts, styles, and technology.
