Sneng

The sneng or snaeng (Khmer: ស្នែង, "horn") is an aerophone made from an ox horn or water buffalo horn.

It is loud enough to call across a distance and has been used in rural environments to signal mealtimes, give warning, call for help or indicate a need to return to the village.

It was also used to call domestic elephants in from the field, and hunters communicated with it.

[1] Two different types of sneng exist:

A side-blown sneng plays, demonstrating the multiple tones possible from the instrument. Side blown instruments may have two fingerholes, one on each end of the instrument. End-blown instruments have no fingerholes and only one note.
