A simple bamboo ring flute found in Indonesia and the Philippines, used in gamelan ensembles.

A notch is cut into the the side of the top end, and this top end is surrounded by a rattan of bamboo ring, leaving a small slit where the player will put his mouth.

 There are 5-hole and 4-hole sulings. Depending on the regional genre, a suling can be tuned into different scales.

With its different color of sound, it provides one of the most expressive lines in the ensemble. It sometimes grouped with the rebab and the voice, but its part is freer. Compared to other counter-melody instruments, its musical phrases are shorter and disjointed.
