Instrument
The gralla (), 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.
This traditional instrument is used during the construction and dismantling of human towers or castells and other traditional festivities. it is usually played with the timbal, a percussion instrument similar to a drum. The traditional "gralla" melody used in castells, called the "toc de castells," serves to advise the castellers within the tower what stage of the construction their colleagues have reached, as they are unable to see this.
The "gralla" regained popularity in the late 1970s.
Types.
There are two types of "gralla", the "seca"(dry) and the "dolça", (sweet). Both can be characterised by their sound: the "gralla seca" has a harsher or strident sound while the "gralla dolça" has metal keys that increase its register.
