sensory introduction by irunak published on 2012/09/22 02:38:52 +0000 an introductory piece for "sensory deprivation" and the first section of "sensory perception", if the 3 were ever lined up that way. sensory introduction combines elements of both. the bits of accompanying chants for boys serve to punctuate or embelish some textures. it so happens the vocals are "polyphonic". I am thinking of other song and "aria" types. the work may sound more present at a higher volume level.
