Musical Expression and Digital Media
The development of new music services was helped enormously by the increasing dialogue with and between media users. Interactivity was an important requirement of Berthold Brecht's radio theory long before the start of the multimedia era. Brecht saw radio not just as a medium of distribution but as a medium of communication. It was digital technology, however, which opened the way to wide-ranging interactive measures in the media landscape. They are found in the music sector in constantly refined forms, providing access to specific media products through analysis of usage, calculated by 'hits' to website files. But more than this, they allow the development of exchange forums about the beauty of music, and of its channels.
