John Cage (1912-1992): Variations II, For any number of players and any sound producing means. Version for amplified piano (1961).

David Tudor, pianoforte.

"I believe that the use of noise to make music will continue and increase until we reach a music produced through the aid of electrical instruments that will make available for musical purposes any and all sounds that can be heard." (John Cage 1937).

The materials of this work consist of 5 small transparencies with a single point each, and 6 larger tranparencies with one line each. These may be superimposed in any way, creating a configuration of the points and lines, to be interpreted as a way of producing sounds. This is done by dropping perpendiculars from the points to all of the lines (creating a total of 30 perpendiculars). Measurements of the perpendiculars are used to obtain readings for frequency, amplitude, timbre, duration, point of occurence in an established period of time and the structure of the event (number of sounds).
