Thon and rammana

The thon and rammana (Thai: โทนรำมะนา,  [tʰoːn ram.ma.naː]) are hand drums played as a pair in Thai classical music. It consists of two drums: the thon (โทน), a goblet drum with a ceramic or wooden body and the rammana (รำมะนา), a small frame drum. They are used usually in the khruang sai ensemble. 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.
