Sralai

The sralai (Khmer: ស្រឡៃ) is a Cambodian wind instrument that uses a quadruple reed to produce sound.

[1] The set of quadruple reeds are made of palm leaf.

"[1][2][3] Its cousin, the Western oboe, has a double reed and a conical bore.

The pinpeat instruments tune to the sralai's pitch, and the player must learn circular breathing to play continuously without stopping for breath.

[1] The sralai is very similar in construction and playing technique to the Thai pi.
