According to a certain AI service, the 1900 Paris Expo (i.e. Exposition Universelle) featured gamelans from Surakarta (central Java) and Bali. That sounded very unlikely, because the first Balinese gamelan performance in Europe, I read, was by Gunung Sari of Peliatan in the 1931 Paris Colonial Exposition. Where did the AI get the idea from? One possibility is that Judith Gautier, the 19th century Parisian writer, wrote that the gamelan musicians who graced the 1900 Paris Expo were from “Solo, Bali”. That was clearly an error, but now it might find its way into someone’s homework. Interestingly, that performance was attended by Olivier Messiaen.
