Sybyzgy is a kind of choor (a sideblown flute on Inner Asian pastoralists) used in Kyrgyz and Kazakh, etc. It is traditionally played by shepherds and horse herders, made from apricot wood or the wood of mountain bushes. The sybyzgy has its own repertory of solo pieces, known as kuu, which are distinguished by their lyrical content.
