The khaen is a bamboo mouth organ from Laos and northeast Thailand that plays melody and chords at the same time. Each bamboo pipe holds a small metal reed, and the player blows and draws air through a wooden wind chest while closing finger holes to choose which pipes sound. “Khaen music of the Lao people” was added to UNESCO’s list of intangible cultural heritage in 2017.
Its buzzing, harmonica-meets-bagpipe sound has made khaen covers of pop songs a regular hit on short-form video.

How the khaen works
- Free reeds: each pipe has a thin metal reed that vibrates freely, the same principle as a harmonica or accordion.
- Breathing both ways: the reeds sound when you blow and when you draw, so players can breathe continuously.
- Finger holes: a pipe only sounds when its hole is covered. Covering several holes plays a chord.
- Drones: players often hold certain pipes throughout a piece, giving the khaen its hypnotic, layered sound.
Modes and music
Traditional khaen music is organised into modes called lai, each with its own scale, drone notes and mood. The khaen is the essential accompaniment to mor lam, a sung storytelling and dance tradition of Laos and Isan, and is heard at festivals, ceremonies and social gatherings. Modern players also use it in pop, jazz and electronic music.
Why the khaen is going viral
- Unfamiliar sound: most viewers have never heard a free-reed mouth organ with drones.
- Pop covers: chart hits played on khaen blend the familiar with the unexpected.
- Visual impact: the long bamboo pipes and the player’s breathing make it striking to watch.

Khaen vs harmonica vs sheng
| Khaen | Harmonica | Sheng | |
|---|---|---|---|
| Origin | Laos / Isan | Europe (19th century) | China |
| Body | Bamboo pipes in two rows | Small metal and plastic body | Pipes in a circular bundle |
| Chords | Yes, freely chosen | Built-in chord layout | Yes |
| Learning curve | Moderate | Easy start | Moderate to hard |
If you like the reedy sound, a harmonica is the easiest place to start; see our harmonica breathing exercises.
Getting a khaen
- Buy from makers or shops connected to Lao or Isan communities where possible; quality varies a lot between tourist souvenirs and playable instruments.
- Check that every pipe sounds when blowing and drawing.
- Ask which mode (lai) and key it suits.
- Keep it away from extreme heat and humidity; bamboo and wax seals can crack or loosen.
Common questions
Is the khaen hard to learn?
The basics are approachable, especially if you have played harmonica. Mastering lai modes and continuous breathing takes longer.
Is the khaen the same as a bamboo flute?
No. Flutes have no reeds; the khaen uses metal reeds, which give its buzzing tone and allow chords.
