The cantu a tenòre (also known in Sardinian language as su tenòre, su cuncòrdu, su cuntràttu, su cussèrtu, s'agorropamèntu, su cantu a pròa) or canto a tenore in Italian is a style of polyphonic folk singing characteristic of the Barbagia region of the island of Sardinia (Italy), even though some other Sardinian sub-regions bear examples of such tradition.
