Real Pan Flute

排箫s的基础上的原理的组乐器

The pan flutes (also known as panpipes) are a group of musical instruments based on the principle of the closed tube, consisting of multiple pipes of gradually increasing length (and occasionally girth). Multiple varieties of panflutes have long been popular as folk instruments. They are considered to be the first mouth organ, ancestor of both the pipe organ and the harmonica[citation needed]. The pipes are typically made from bamboo, giant cane, or local reeds. Other materials include wood, plastic, metal and ivory.
