Sac de gemecs

The sac de gemecs is a type of bagpipes found in Catalonia.
The instrument consists of a chanter, a mouthblown blowpipe, and three drones. The lowest drone plays a note two octaves below the tonic of the chanter. The middle drone plays a fifth above the bass. The high drone plays an octave below the chanter, thus one octave above the bass drone.

Folklore

The instrument figures into the Andorran legend El buner d'Ordino, in which a bagpiper from the parish of Ordino, en route to a festival in Canillo, is chased and treed by wolves, but frightens them off by playing his buna.
