Telefax Score No. 1 transforms an ordinary fax message into a musical piece for 10 instruments. Technically the transmission of a fax message is a series of tone-sequences that are sent over the telephone line. In Telefax Score No. 1 all those tones were recorded, slowed down to a playable sound piece and transcribed into a score for 16 classical instruments. The whole digital information of a fax message was notated on 21 sheets.
The sender transmits a Digital Command Signal (DCS), which specifies the transmission parameters.
