Hornbostel - Sachs
Sets of gongs
Sets of metal 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 struck surface is divided to create notes of different pitches and the vibration is strongest near the vertex of each struck section. The player creates clearly defined individual strokes. Steel drums, Caribbean.
