Hornbostel - Sachs
(Sets of) suspended bells
Sets of percussion vessels, owing to the solidity and elasticity of their substance, vibrate and radiate sound when struck with non-sonorous objects (hand, stick, striker). The vibration is weakest near the apex from which each instrument is suspended. The player creates clearly defined individual strokes on the exterior surfaces of the bells, using attached external strikers (clappers).
