Ivan Alexandrovich Wyschnegradsky (Ива́н Алекса́ндрович Вышнегра́дский) was a Russian composer primarily known for his microtonal compositions.

Pascal Criton, a french composer of contemporary music as well as a musicologist who studied Wyschnegradsky’s works, created an interactive piece inspired by Wyschnegradsky’s “ultrachromatic compositions” for association Puce Muse.

I designed a collective instrument able to produce complex polyrhytmic sequences of filtered sound texture. Each step of the sequence can be assigned a color nuance and a pitch, possibly micro-tonal. The result produces visual and sonic moires, reminding of Wyschnegradsky’s chromatic drawings.
