Yak (instrument)

The yak (Korean: 약) is a small flute used vertically, which has three holes and is used in court music.

This wind instrument was called a wiyak because it was made of reeds, not bamboo.

Originally an instrument used in the Chinese "aak", the yak arrived in Korea during the Koryo dynasty and was used during the performance of cultural dances.

The yak was originally formed from a reed plant, but is now built primarily of wood.

[5] Due to these typing difficulties, it is only used for very slow music without grace notes.
