Description: A chap or chhap [Thai: ฉาบ, Khmer: ឆាប] are a pair of symbols made from bronze. The chapp consists of two thin, round disks or plates with a bulge in the center. The plates are held against the hands like cymbals, using handles made of string, passing through a hole in the center of each plate.
The name comes from the sound the instrument makes when struck directly together, “chapp, chapp.” The “timbre or tone” change when struck at an angle.
