Joseph Hyde is an composer, performer and audiovisual artist with a background in classical music and sound art. He also teaches and supervises PhDs in these areas at Bath Spa University (UK), and writes extensively about ‘visual music’. He has undertaken a project on the unique musical notation used by animation and visual music pioneer Oskar Fischinger, and in his creative practice he has focused on the use of ‘obsolete’ technologies: cathode ray tubes, oscilloscopes and analogue (audio and video) synthesisers. Since 2009 he has run a symposium on visual music at Bath Spa University, Seeing Sound.
