Handmade bamboo pan flute with 15 tone tubes in C-G tuning, ideal for use in folk music. Pan flute is an instrument commonly used in South America, even though it is named after Pam. The Greek god of nature often depicted with such an instrument. Its sound is produced by the vibration of an air-stream blowing across an open hole at the end of a resonating tube. Pan flutes are considered to be the first mouth organ, ancestor of both the pipe organ and the harmonica.
