The instrument isn't 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 used for all kinds of occasions, especially for festivals and ceremonies. The instrument can be played solo or in an ensemble.
