Junggeum

The junggeum (also spelled chunggum or chunggŭm) is a medium-sized bamboo transverse flute formerly used in traditional Korean music. Unlike the larger daegeum, it does not have a buzzing membrane (although it did have one in ancient times).[1] It was used in court, aristocratic, and folk music, but has largely died out, being rarely used today.

Other flutes in the same family include the daegeum and sogeum; the three together are known as samjuk (hangul: 삼죽; hanja: 三竹; literally "three bamboo"), as the three primary flutes of the Silla period.[2] Both of these are still used in traditional music, as well as in contemporary classical music, popular music, and film scores.
