Nicolas Bras demonstrates the acoustics of various PVC woodwind and brass instruments

We all know about Blue Man Group and their impressive percussion PVC instruments. But it turns out, as Nicolas Bras aptly demonstrates, the versatile plastic can also create convincing woodwind and brass instruments that, somewhat ironically, are neither wood nor brass (although as he points out, real life instruments can break those rules as well). It’s a real joy to watch him cobble together some pipes and make beautiful noise with them, but it’s also a great lesson in acoustics and a demonstration of the fact that it’s the way the air is vibrated, not the material of the instrument, that defines it. Highlight: That three-headed serpentine instrument he makes to play three notes at once.
