The ranat thum (Template:Lang-th, pronounced [ranâːt tʰúm]) is a low pitched xylophone used in the music of Thailand. It has 18 wooden keys, which are stretched over a boat-shaped trough resonator. Its shape looks like a ranat ek, but it is lower and wider. It is usually played in accompaniment of a ranat ek.
ranat thum bars are typically made from bamboo, although instruments with rosewood (Dalbergia oliveri; Template:Lang-th; mai ching chan) bars can also be found.
It is similar to a Cambodian xylophone called roneat thung.
