What does "Plays Didgeridoo" mean?

[SUDHAKAR Kuruvada]

The didgeridoo is an Australian Aboriginal wind musical instrument. They were used by the Yolgnu people of Arnhem Lan It is best described as being a wooden trumpet or drone. Musicologists say it is a brass aerophone.
The didgeridoo is a rhythm instrument, so you play "beats" instead of melodic songs. Play at your own speed as well: quiet or loud, fast or slow... you'll develop your own style. There are no rules or complex memorization. This makes learning the instrument very intuitive, so you don't need any musical training or years of lessons to enjoy playing the didgeridoo straight away.
