About 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 that 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 pieces of other tapes, changed the order of playing, made them play faster! Today, with technology, we can compose music like Pierre Schaeffer's, using only a cell phone, a tablet, or a computer. In this workshop we will become composers of concrete music and the sounds around us will become amazing sound pieces!
