Rattling, metallic, bright, brilliant, silvery, festive, sparkling, shuffling, jingling, rustling.
The sound of the tambourine has solely the properties of noise and is composed of the attack when the head is struck and the characteristic rattling of the jingles.
Because the head is tightly braced it has no resonance.
The brightness of the jingles means that the tambourine can still be heard in the midst of other orchestra instruments. A shaken fortissimo roll is still plainly audible even in tutti passages.
