About chiba

Chiba is a Chinese vertical end-blown flute and one type of xiao. It is one of the oldest Chinese woodwind instruments. Unlike the northern xiao, it bears resemblance to most of the southern xiao, in that it is shorter, wider, has an open mouthpiece, slightly conical, and generally has a root end. The name chiba refers to its length, where chǐ is a Chinese foot unit and bā means eight.
