Pong lang

The pong lang (Thai: โปงลาง, RTGS: ponglang, Thai pronunciation: [pōːŋ.lāːŋ]) is a xylophone from the Isan region of northeast Thailand. The instrument may be played as a standalone instrument, in pairs with one player playing melody and the other harmonizing, or as part of an orchestra. Players use carved two hardwood mallets. The instrument is not standardized and the number of tone bars and their size can vary.
