The image shown is a mouth organ called a khaen from Thailand. It is made of bamboo and has canes of various lengths and diameters. The wooden mouthpiece holds canes with a putty-like material. Khaen are also found in Laos and Cambodia.

The exact origin of the khaen is uncertain, but it is believed to have originated in Laos or Northeast Thailand more than 1,000 years ago. The instrument has been used in the traditional music of various ethnic groups in the region, including the Lao, Thai, and Hmong. The khaen has a significant cultural and spiritual significance in these communities, and it is often played at festivals, weddings, and funerals.
