Kamu-purrui is written for alto flute with open holes. The title refers to a specific type of South American flutes by the Cuna indians that allow the performer to produce two sounds at the same time. This is achieved in the piece by the simultaneous emission of the performer’s voice and the instrumental sound.

Kamu-purrui is dedicated to Carlo Ipata, whose knowledge and enthusiasm have proved invaluable in the realisation of this work.
