The teukgyeong consists of a single pumice slab. The percussionist strikes the pumice slab with a mallet to produce the tone, tuned to the note c, one octave above the teukjong. The teukgyeong is simply a single-tone version of the splendid pyeongyeong. In the 15th century the teukgyeong was used in both the deungga (terrace orchestra) and the hunga (courtyard orchestra) but today it is only used in the deungga for performances of both the Confucian Shrine Ceremony and the Royal Ancestral Shrine Ceremony.
Used to signal the end of the music. When a performance ends.
