Sardinia is probably the most culturally distinct of all the regions in Italy and, musically, is best known for the tenore polyphonic singing, sacred chants called gosos, the launeddas, an ancient instrument that consists of a set of three single-reed pipes, all three mouth-blown simultaneously using circular breathing, with two chanters and one drone and the cantu a chiterra, a monodic song that is accompanied by guitar, widespread mainly in the center and north of the island.
