Daegeum

The daegeum (also spelled taegum, daegum or taegŭm) is a large bamboo flute, a transverse flute used in traditional Korean music. It has a buzzing acoustic membrane. It is used in court, aristocratic, and folk music, as well as in contemporary classical music, popular music, and film scores. And daegeum has a wide range and has a fixed pitch, so other instruments tune in to the daegeum when playing together.
