Exposiciones for Sampled Microtonal Schoenhut Toy Piano is an 'acousmatic' work that attempts to explore the equally-tempered sound world within the context of a sampled microtonal Schoenhut model 6625, 25-key toy piano and a complex polyrhythmic scheme. All equal temperaments between 1 and 24 - essentially functioning as tuning modulations - as well as all polyrhythms (divisible only by 1 and including their inversions) between the ranges of 2 and 15 are presented. In other words, polyrhythmic ratios 3:2 (2:3), 5:2 (2:5), 4:3 (3:4), 5:3 (3:5), and so on - 57 polyrhythmic sets in total, with the last set represented by 15:14 (14:15) - alongside two complementary scales (Indonesian Pélog and Sléndro forms with primary and secondary scale tones, as well as primary and secondary auxiliary tones) shaped via microtonal inflections produced by sequential tuning modulations featuring the first 24 equally-tempered divisions of the octave.
Instrumentation: 4-channel, 5-channel, 6-channel, 7-channel, or 8-channel sound diffusion system required.
