Diffusion Score

Musicology of Electroacoustic Music [MEM]  >  Analysis  >  Structural Analysis  >  Visual Representation  ]

Normally used as an aide-mémoire for electroacoustic performance, a diffusion score is generally a high level visual representation of apiece, that notates, often in a highly personal fashion those salient aural details necessary for the performer’s interpretation. Often hand-drawn and utilising symbols particular to the maker of the score, a common approach is to represent time on a horizontal axis and spectrum in the vertical. Sometimes high level or edited computer-based visualisations are used in diffusion. Diffusion scores are normally not of great assistance to an analyst except as an overall ’map’ of a piece’s structure.
