[1] It consists of a bag made of skin (or modern synthetic materials), known as a sac or sarró which retains the air, a blowpipe (bufador), a melody pipe or chanter (grall), and several, generally three, drones (bordons).
This is related to the influence of Occitania during the Kingdom of Aragon, as Catalan was quite strong from the year 531 to approximately 1131, as the Occitan cultural centre expanded through the means of minstrels and bards, throughout the territory that would later be known as Catalonia.
The first written reference dates to the 9th century, in a letter from Saint Jerome to Dardanus: "The chorus is a simple leather hide with two brass tubes.
The player blows into one, and the chorus emits the sound through the other".The influence of the court of Aragon and particularly that of Catalonia in the Balearic Islands and the cultural exchanges on both sides of the Pyrenees together with Catalan hegemony in Occitania, which had been a strong cultural center, caused an increase the number of bards and minstrels increased.
In 1209 there was a massive migration of bards and minstrels fleeing Occitania, due to repression by the northern French monarchs, encouraged by Pope Innocent III.
Further, it is known that the minstrels of the king of Mallorca brought to the court of Peter IV the ceremonial playing of the bagpipe through the city of Tortosa in the year 1353.
During the reign of Alfonso V of Aragon and IV of Catalonia, called The Magnanimous the instrument spread, along with other cultural trappings, to the kingdom's possessions in the Mediterranean.
Though it faded from popularity in other Catalan territories, this was not the case of the Balearic Islands where isolation and a predominantly rural population preserved the instrument within the culture.
The xeremia, close relative of the sac de gemecs, maintains its popularity in the culture of the Baleares even as native bagpiping traditions across Europe went into decline.
