A didgeridoo is a long wooden tube, played especially by Aboriginal people in Australia. You blow with shaking lips so the air hums, and you can breathe in through the nose while you still blow, so the low sound does not stop. It is not a flute with finger holes; your mouth and throat change the sound. The traditional ones are often a long piece of wood that insects have already made hollow. The English name is probably an attempt to copy the sound: a visitor in 1829 wrote something like didoggerry whoan. Some people have guessed at Irish or Scottish Gaelic words for a piper, but that is a thin story with little to back it, and those words would name a player, not the instrument. Keep the sound-copying explanation. You may also see the spelling didjeridu. Treat the instrument as part of a living culture, not a toy name.
