Pey au

The pey au (sometimes spelled pei au or pei ar) (Khmer: ប៉ីអ) is a Cambodian musical instrument, similar to a flute but using a set of double reeds to produce sound.

[1][2] The instrument uses an external reed, cut from a prebos[check spelling] tree and flattened with small strips of ratan.

[2] The bundle is insterted into a hold at the top of the flute part of the instrument, creating a mouthpiece.
