danso

thumb|Danso fingering chart (all pitches sound one octave higher than written)|400px The danso (also spelled tanso) is a Korean notched, end-blown vertical bamboo flute used in Korean folk music. It is traditionally made of bamboo, but since the 20th century it has also been made of plastic. It was imported from China in the 19th century, where it is called duanxiao (). The Korean name is the transliteration of the Chinese one, a short variant of the xiao.

The flute has four finger holes and one thumb hole at the back. The playing range is two octaves, going from low G to high G. The lower sounds are made by just blowing, whereas the higher ones are made by difference in the strength of the blowing. The tone is clear, and it is also used as a solo instrument, but is mainly used for ensemble with other instruments in chamber music.
