From the Website:
Music is for everyone. So this year for Music In Our Schools month, we wanted to make learning music a bit more accessible to everyone by using technology that’s open to everyone: the web. Chrome Music Lab is a collection of experiments that let anyone, at any age, explore how music works. They’re collaborations between musicians and coders, all built with the freely available Web Audio API. These experiments are just a start. Check out each experiment to find open-source code you can use to build your own.
