Saenghwang | Taepyongso | Piri
The saenghwang is a Korean wind instrument. It is a free reed mouth organ derived from (and quite similar to) the Chinese sheng, though its°Ø tuning is different. It is constructed from 17 bamboo pipes, each with a metal free reed, mounted vertically in a windchest. Traditionally the saenghwang's windchest was made out of a dried gourd but nowadays it is more commonly made of metal or wood. In contrast to other Korean traditional instruments, it is not well known today, even in Korea, and very few musicians are able to play it. It is used primarily in chamber music, usually in combination with instruments such as the danso (vertical flute) and yanggeum (hammered dulcimer). The instrument was referred to historically as sang.
The taepyeongso (lit. "big peace wind instrument"; also called hojok, hojeok nallari, or saenap) is a Korean double reed wind instrument in the shawm or oboe family, probably descended from the Persian zurna and closely related to the Chinese suona. It has a conical wooden body made from yuja (citron), daechu (jujube), or yellow mulberry wood, with a metal mouthpiece and cup-shaped metal bell. The loud and piercing sound it produces has kept it confined mostly to Korean folk music and to marching bands. It is, however, also used sparingly in other genres, including Confucian, Buddhist and Shamanist ritual musics.
The piri is a cylindrical double-reed bamboo oboe with eight finger holes, one in the back for the thumb and seven in the front. Its°Ø large reed and cylindrical bore gives it a sound mellower than that of many other types of oboe. The piri is an essential instrument and popularly used in both folk and classical court music. There are other piris named hyang piri and dang (Tang) piri classified by the periods they were imported from China.
