Talk:Graphic Scores-avant-garde

• description of sound gestures s such noise, extended playing techniques (e.g. rubbing fingers on skin, bowing a cymbal, processing the sound, etc) that fall outside the scope of western musical notation
• description of the instrument configurations and setting of an instrument (e.g. the patch of modular synthesizer or preparation of a piano)
• capacity to change the form of the composition significantly, with each interpretation
• capacity to change the roles and responsibilities of composer and interpret

John Cartridge Music (1960)

Score elements:

• 1 page of instructions,
• 4 transparent sheets: one with points, one with circles, another with a circle that looks like a clock face, and a fourth with a dotted curved line with a circle at the end of it
• 20 pieces of white paper with shapes on them.

Placement: superimpose the transparencies over the sheet with shapes to get a determination for playing. You may place the sheets randomly, one on top of the other, only making sure that the circle at the end of the dotted line contains a point outside a shape and that the dotted line intersects at least one point within a shape.

Instruction: Curved dotted line: is read from beginning to end (marked with a circle)

Points and circles represent events in the performance:

• when intersected by dotted line
  • points are:
    • sounds on (inside a shape) corresponding to that shape
    • sounds off (outside a shape) the cartridge, meaning sounds made by other means than those made by the objects in the cartridges
  • circles: mark changes of amplitude (inside a shape) or tone (outside a shape)
  • circle boundary of a shape: change of object

Clock face intersections by dotted line:

• enter: starting time.
• exit: ending time.
