Denis Smalley’s Spectromorphological theory makes consideration of listening responses to ’extrinsic’ (or referential) aspects of sound materials in its explanation of gesture/texture as a structuring principle in electroacoustic music composition and analysis. Nine indicative or ’extrinsic’ attributes are identified as being of significance:
gesture, utterance, behaviour, energy, motion, object/substance, environment, vision, and space.
