Skor chhaiyam
The skor chhaiyam is a tall Cambodian goblet drum, slung over the shoulder with a string, so it can be played at waist level while walking. Only the top has skin, leaving a sound-hole at the bottom of a narrowed drum body. The instrument is used to "celebrate happy events."
There are 4-5 different varieties of Sklor chhaiyam, designed for different volume levels.
