The gralla (Catalan pronunciation: [ˈɡɾaʎə]), also known as grall de pastor, xaramita or xirimita, is a traditional Catalan double reed instrument in the shawm family classified in the group 422.112 in the Hornbostel-Sachs system. Like the dolçaina from Valencia – a very similar instrument that many experts consider a variety of the gralla –. The gralla comes from the ancient xeremia a medieval instrument largely used until the Baroque. Probably, the name of the instrument comes from its strident sound similar to the sound of a Jackdaw native to Catalonia and northern Spain and also called 'Gralla' in Catalan.
