A piphat is a kind of ensemble in the classical music of Thailand, which features wind and percussion instruments. It is considered the primary form of ensemble for the interpretation of the most sacred and 'high-class' compositions of the Thai classical repertoire, including the Buddhist invocation entitled sathukan as well as the suites called phleng rueang. It is also used to accompany traditional Thai theatrical and dance forms including khon (masked dance-drama), lakhon (classical dance), and shadow puppet theater.
