[3] According to another source, Cambodian Roneat genres were derived from the Javanese gamelan musical instruments which influenced the Khmer musical instrument in the early Angkorian period which spread from Kampuchea further northwest to Myanmar.

[4] Specifically, Roneat Thung is identical to the Indonesian and Malay gambang kayu.

Roneat thung's rectangular trough-resonator measures about 50 inches long supported by four short legs.

As the materials, which are used to make the bars, are the same as the roneat aek, the same tuning blobs are also utilized.

The roneat thung plays a line almost identical to that of the korng thomm, except in a lak (vivacious, funny, comic) fashion.

[7] Roneat Thung has significant function in Khmer traditional orchestra both Pinpeat and Mohaori.
