Emma Hersh - Instrument: Didgeridoo

It's played by blowing raspberries through the mouth of the instrument, this sends waves through the body of the instrument and then out the bottom. Sometimes the bottom is bigger than the top so that the sound funnels and vibrates out, but the instrument makes the same sound without a larger bottom. It's shaped like a regular shaped tube, but it's usually wood and sometimes has fancy painting on the outside. You change note by blowing harder or softer and opening your throat like you would in singing to change pitch. I think sound waves vibrate from your lips down the body of the instrument and then out the bottom to create a low pitched humming noise.
