Canone Effimero is a journey to discover an underground and unseen Italy, far from current narratives. The protagonists of this in-depth study are people who struggle, in their small local communities, for the survival of certain musical expressions of their oral tradition, against the tide of an increasingly strong general cultural homogenization. Young girls of Arbëreshë origin, elderly shepherds and passionate researchers are the faces and stories that make up the framework and sentiment of this epic and fragmented journey, grappling with the polyvocal songs of some interstitial areas of our territory, but also with the construction of ancient instruments and the use of so-called ephemeral instruments, languages that are rooted deep in popular culture.
