During the first stage of a two part residency with the research group Espaces Sonores, a collective working out of the Haute École des Arts du Rhin in both Mulhouse and Strasbourg, and the conservatoire in Strasbourg, I made some tests to make simple sound-making devices that use found and everyday objects.
I'm thinking that for workshops it would be nice to conceal what is happening inside the box, so at the end of the sessions we will gather them together and these seemingly uniform objects will all have a different characteristic 'voice'.
