Thon and rammana

The thon and rammana are hand drums played as a pair in Khmer and Thai classical music. It consists of two drums: the thon (Khmer: ស្គរថូន;Thai: โทน), a goblet drum with a ceramic or wooden body and the rammana (Khmer: ស្គររមនា;Thai: รำมะนา), a small rebana-typed frame drum or tambourine. They are used usually in the Mohaori ensemble in Cambodia and khruang sai ensemble in Thailand. The thon gives a low pitch and the rammana gives a high pitch.

Earlier in the 20th century, the thon and rammana were sometimes played separately.
