The Cantu a tenore is a style of polyphonic folk singing characteristic of the Barbagia region of the island, even though some other Sardinian sub-regions bear examples of such tradition.

In the last few years they've been touring extensively Europe (France, Germany, Denmark, Norway, Czech Republic, Spain, Belgium, Nederland, Austria, Luxembourg, Slovenia, Swiss, Ireland, Croatia, Serbia, Lithuania, Estonia, Poland, Tunisia, Hungary, United Arab Emirates, Brazil and Japan).

The Tenores di Bitti "Mialinu Pira", having performed for so many years, is nowadays considered from music-fans and ethno-musicologists the most prominent example of this vocal art.

Both in dancing (lestru, dillu, seriu, passu torrau,) and slow (isterrita, boch'e notte) forms, the lyrics, by famous poets or from misknown contemporary authors, make the repertoire of Tenores di Bitti "Mialinu Pira" an important vehicle of literary transmission.

It is no mere coincidence that the experts think that it may have had its origin in primitive times as an imitation of nature: the four voices of which the choir is composed is no more than the lowing of cattle, the bleating of sheep and the sound of the wind.
