2. Pyenchong (Bell-Chimes): This instrument is made up of 16 bronze bells, two rows of eight each, which hang in a carved standard. The bells are identical in shape and size, but different in thickness. The thicker the bell, the higher the tone. These bell-chimes, together with the stone-chimes called Pyenkyong, are indispensable to the traditional Korean court music and are now used during the ceremonial music at Chongmyo, the ancestral temple of the royal family, and the Confucian Temple.
