Clapstick

Clapsticks, also spelt clap sticks and also known as bilma, bimli, clappers, musicstick or just stick, are a traditional Australian Aboriginal instrument. They serve to maintain rhythm in voice chants, often as part of an Aboriginal ceremony. They are a type of drumstick, percussion mallet or claves that belongs to the idiophone category. Unlike drumsticks, which are generally used to strike a drum, clapsticks are intended for striking one stick on another.
