The pong lang (Thai: โปงลาง, RTGS: ponglang, Thai pronunciation: [pōːŋ.lāːŋ]) is a xylophone from the Isan region of northeast Thailand.^[1][2] 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.^[2] Players use carved two hardwood mallets.^[2]

The instrument is not standardized and the number of tone bars and their size can vary.^[2] Unlike the ranat ek lek and ranat thum lek which are strung over a box, the pong lang is hung from a post or tree with the string of tone bars arcing down toward the ground.^[2] wide to short. The number of tone bars varies, and 12 or 15 tone bars may make up a set. The wider bars with lower pitch sit at the top of the string and the other end (with smaller high-pitched bars) may be hooked to the player's toe or to a belt around the player's waist.^[2]

When there are two performers, they may sit on opposite sides of the post, facing one another. With two instruments, one plays the melody, the other plays a drone accompaniment or harmonics.^[2] The pong lang is mostly used for many occasions, especially for festivals and ceremonies. The instrument can be played solo or in an ensemble.
