The mahori, possibly from Sanskrit मनोहर + -ई, is a form of Thai classical ensemble traditionally played in the royal courts for the purpose of secular entertainment. It combines the xylophones and gong circles of the piphat with the strings of the khruang sai ensemble. Originally, the term referred only to a string ensemble, although today it includes both string and percussion. There are three broad types of Mahori: Mahori Khryang Lek, Mahori Khyrang Khu, and Mahori Khyrang Yai, each differentiated by the types of instruments utilized. It is comparable to the Cambodian mohaori ensemble.

The khong wong yai is a circle with gongs used in the music of Thailand. It has 16 tuned bossed gongs in a rattan frame and is played with two beaters. The player sits in the center of the circle. It is used in the piphat ensemble to provide the skeletal melody the other instruments of the elaborate ensemble. The gongs are individually tuned with beeswax under the gongs. The khong wong yai can either be played with soft beaters or hard beaters.
