Generally, composers of electroacoustic music do not make visual scores of their works. Notable exceptions to this might include:
a score of procedures to enable others to recreate a piece
a representation of electroacoustic material to aid an instrumentalist or vocalist in a Mixed Work
a representation of how sound materials on a fixed medium should be routed to apparent spatial sources in a complex performance or installation situation
Since the signifying and structuring features of electroacoustic music do not conform to agreed upon saliences, as is the case with most notated instrumental and vocal compositions, the strategies for visually representing music may vary enormously between different graphic scores.
