How does a vuvuzela work, anyway? Does it have a reed? Is it a kazoo? Do you vibrate your lips against a mouthpiece as with a trumpet, as the pictures imply? If so, why is its one note much lower than it should be (it sounds like the fundamental of a pipe about five feet long), and why doesn’t anyone seem to be able to produce harmonics above that monotone buzz? (While I’m at it, how does a shofar produce such a low note?)
This explanation is probably wrong, because as we know bees have become scarce owing to disease and mites while vuvuzelas threaten to cover the planet. Please comment if you know what’s inside these things.
