The ulla (Korean: Script error: No such module "Lang".; Hanja: Script error: No such module "Lang".Template:Category handler) is a traditional Korean percussion instrument comprising a set of ten small tuned gongs in a wooden frame. They are struck with a mallet.[1][2] Each of the gongs are the same size, but they produce different sounds due to their differing thickness.[2]
It is also called guunra (Script error: No such module "Lang".; Script error: No such module "Lang".Template:Category handler) or uno (Script error: No such module "Lang".; Script error: No such module "Lang".Template:Category handler).[2] The instrument is attested to during the Joseon period.[2]
The ulla is derived from the Chinese yunluo.
