"Simon Mawhinney’s short Music for 1 Channel was the only monaural piece I have heard on a festival like this – ever, I think. It consisted of a series of three sine waves which were presented over and over in different, odd tunings, creating interesting beating effects, each tone fading in and out at a different rate from the others. As the composer said in his notes, "this creates audio-illusions which our brains interpret as little patterns." It was like a minimalist etude, but far more interesting than anything else I would apply the "minimalist" adjective to."
