Yunluo

[1] It is made up of a set of gongs of varying sizes held within a frame.

Old drawings also depict a smaller yunluo with just five gongs, which was held by a handle by one hand and played with the other.

A very similar instrument called the ulla (hangul: 운라; hanja: 雲鑼 or 雲羅), which is derived from the yunluo, is used in the music of Korea.

The ulla was introduced from the Qing Dynasty in the late Joseon Dynasty is presumed to have been used in haengak (hangul: 행악; hanja: 行樂; royal court music played in procession).
