OneTwo Procedure


Le forchette di tempo sono uniche per i due interpreti/improvvisatori. Ogni forchetta di tempo deve sempre essere intesa come duo. I tempi tra le forchette sono intesi come solo.

Questi tempi/spazi in solo non devono essere concordati prima ma raggiunti durante l’improvvisazione attraverso l’ascolto e l’immersione nel paesaggio sonoro nella durata complessiva di 22:27 e 18:46. Ci deve essere una pausa di almeno 5 secondi tra la prima e la seconda parte. Nella prima parte le forchette di tempo tra parentesi sono a scelta, sempre come duo.




The time bracket(s) are unique to the two interpreters / improvisers. Every fork of time must always be understood as a duo. The times between the bracket(s) are understood as only. These times / spaces in solo do not have to be agreed before but reached during the improvisation through the listening and the immersion in the sound landscape in the total duration of 22:27 and 18:46. There must be a pause of at least 5 seconds between the first and second part. In the first part the time brackets in (5:16 to 7:27) / (6:02 to 9:01) are chosen, always as a duo.
