It’s hard to find in such a limited geographical area (the island has an area of just under 24 thousand square kilometres and a population of 1 million 600 thousand inhabitants) a musical heritage as rich and varied expressions such as what we can find in Sardinia. Sardinian traditional music is one of the richest and oldest in the Mediterranean and is manifested in choral canto and use of tools some of which are typical of the island.
One of the most original Islander heritage is undoubtedly the CANTO A Tenores. It is a choral composed of four male voices typical from Barbagia, in central Sardinia. Also in Sardinia, there are many of these re-enactments. One however, is particularly loved by the Sardinians.
The conductive item, called Boghe, plays the base music on poetic verses which are the main source of the repertoire and that meet various metric forms, the other voices are the bassu, which keeps the same tone of voice soloist with grave and nasal tone that distinguishes it from contra sa, and sa mesa oghe with a sharp tone.
"A situation of dense complexity" it is the definition of heritage in Sardinia by the anthropologist Alberto Maria Cirese. And it is true indeed. Vital traditions, now lost in other parts of the Mediterranean, still survive in Sardinia: feasts, popular believes, of wisdom and respect for the elderly, hospitality and solidarity towards all.
