@benjamingeer@piaille.fr @lameensouag.bsky.social@bsky.brid.gy Michel Giacometti was an ethnomusicologist from Corsica that worked in Portugal during the last century. One of the things that strike him was the similarities between polyphonic song tradition from Corsica and the ones he found in Portugal. The origin of those similarities in Mediterranean music is highly debatable. Probably they have a roman liturgical origin with posterior oriental/arabic contributions. https://pt.wikipedia.org/wiki/Michel_Giacometti
