70 years ago in Paris, Pierre Schaeffer created a new way of composing music. He called it concrete music. Pierre and his colleagues listened to concrete sounds (the sounds which exist around us) and recorded, manipulated, distorted and combined them to create new musical compositions. Everything was done by hand: they cut pieces of tape, glued them to other pieces of tape, changed the order of playing, and made them play faster! Today, with technology, we can compose music like Pierre Schaeffer's using only a mobile phone, a tablet, or a computer. In this workshop we will become composers of concrete music and the sounds around us will become incredible pieces!
