In 1953 he created the “Ultralettrisme", a form of electro-acoustic extended vocal technique which he described as "Crirythme" which had no 'score' and existed for recording tape alone.
The "Crirythme" explored the voice as a noise source revealing the nonabstracted essence of things much in the tradition of Antonin Artaud's Pour en finir avec le Jugement de Dieu, the brutist orchestras of Dada, and Luigi Russolo's "L'arte dei rumori".
