Sac de gemecs

The sac de gemecs (Catalan: literally "bag of moans", alternately buna in Andorra or coixinera, gaita or botella) is a type of bagpipe found in Catalonia (eastern Spain spilling over into southern France).

The instrument consists of a chanter, a mouthblown blowpipe, and three drones. The lowest drone (bordó llarg) plays a note two octaves below the tonic of the chanter. The middle drone (bordó mitjà ) plays a fifth above the bass. The high drone (bordó petit) plays an octave below the chanter, thus one octave above the bass drone.
