Pat waing

The pat waing (Burmese: ပတ်ဝိုင်း) or pat wang (Mon: ဗာတ်ဝိုၚ်) is a drum circle instrument used in the Burmese folk musical ensemble (hsaing waing). This instrument has been adapted into the Thai piphat mon ensemble, where it is called poeng mang.

The player sits in the middle of a horseshoe-shaped shell made of elaborately carved wood and decorated with gold leaf. The 21 drums are played with the bare hands. Originally known as the saing waing because the drums were hung on eight carved wooden plunks in a circle, the instrument is now generally referred to as a pat waing.
