A course at the University of Michigan ends with a live concert featuring students using iPhones as instruments. “Building a Mobile Phone Ensemble“ teaches students to code musical instruments for the iPhone, using the Apple-provided software-development kit. Georg Essl, assistant professor of computer science and music, says, "What’s interesting is we blend the whole process. We start from nothing. We teach the programming of iPhones for multimedia stuff, and then we teach students to build their own instruments.”
