Beiguan is a type of traditional music, melody and theatrical performance between the 17th and mid-20th centuries. It was widespread in Taiwan. By the early 21st century its popularity had declined precipitously.
Beiguan usually uses the following instruments: two suona (oboes), bangzi (woodblock), daluo (large bossed gong), xiaoluo (small gong), bangu (high-pitched drum), tonggu (small drum), xiaobo (small cymbals), and dabo (large cymbals) and pipa. It may also use dagu (large drum), various huqin, and plucked instruments.
