The quijada [charrasga, or jawbone in English] is a traditional Latin percussion instrument traditionally made from the jawbone of either a mule, horse, or donkey. The jawbone is cleaned of tissue and dried so the teeth can loosen and act as a rattle. To play, a musician holds one half in one hand and strikes the other with either a stick or their hand; this causes the teeth to rattle against the bone creating a loud, untuned sound, original to this instrument. It is used in music throughout most of Latin America, including Mexico, Peru, El Salvador, Ecuador, and Cuba.
