Since the Millennium, silent films have become more popular than they have been since the 1920s when they were seemingly made obsolete by films with synchronized recorded sound. Their revival has come partly through a rebranding of past culture as heritage often restaged as live event, but perhaps more pertinently through the addition of new musical accompaniments. This novel culture can allow new opportunities for music and a rethink of the place of old silent films in contemporary culture, and this chapter reviews the possibilities and looks at some of the boldest and most controversial ‘modernizations’ of old silent films with new music.
