This weekly concert series consists of professional polyphonic performances held in the largest church in Corsica during the early summer.[4] Rooted in the island’s oral tradition the program highlights the UNESCO-recognized art of Paghjella within its natural liturgical environment. The regional identity is expressed through the acoustic power of the human voice interacting with the baroque grandeur of the church. Visitors enjoy an immersive 60-minute session that provides a profound introduction to the island’s secular and sacred musical structures. The social impact strengthens the cultural economy of the old port area and supports local singers during the shoulder season. For researchers it serves as a living documentation of the persistence of communal singing in the Mediterranean. Preserving these vocal techniques is essential for the transmission of the island’s unique intangible heritage.
