Answer: laos
Explanation:The khene (/ˈkɛn/; spelled "Can" in English; Lao: ແຄນ; Thai: แคน, RTGS: khaen, pronounced [kʰɛ̄ːn]; Khmer: គែន - Ken; Vietnamese: khèn) is a Lao mouth organ whose pipes, which are usually made of bamboo, are connected with a small, hollowed-out hardwood reservoir into which air is blown. The khene is the national instrument of Laos.[1][2] The khene music is an integral part of Lao life that promotes family and social cohesion[3] and it was inscribed in 2017 on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.[4] Today associated with the Lao people of Laos and Isan (Northeast Thailand), other similar instruments date back to the Bronze Age. In Cambodia, it is used among the ethnic Lao population of the province of Stung Treng and is used in lakhon ken, a Cambodian dance drama genre that features the khene as the premiere instrument.[5][6] In Vietnam, this instrument is used among the Tai peoples and the Muong people. The most interesting characteristic of the khene is its free reed, which is made of brass or silver. It is related to Western free-reed instruments such as the harmonium, concertina, accordion, harmonica, and bandoneon, which were developed beginning in the 18th century from the Chinese sheng, a related instrument, a specimen of which had been carried to St. Petersburg, Russia.
The khene has five different lai, or pentatonic modes with specific drone pitches, organized into two families (thang san and thang yao). The thang san family includes lai sutsanaen (G A C D E), lai po sai (C D F G A), and lai soi (D E G A B), while the thang yao family includes lai yai (A C D E G) and lai noi (D F G A C). Lai po sai is considered to be the oldest of the modes and lai sutsanaen the "Father of the Lai Khaen."[citation needed] Khene can be played as a solo instrument (dio khene), as part of an ensemble (such as wong pong lang and khene wong), or as an accompaniment to a Lao or Isan solo singer mor lam. It is often played in combination with a traditional fretted plucked lute called phin.
Composers who have written notated music for the instrument include Annea Lockwood, Christopher Adler, David Loeb, Sidney Marquez Boquiren, Christopher Burns, Jinhee Han, H. James Harkins, Jeff Herriott, Vera Ivanova, and Yu Kuwabara.
