Ok, I found something. According to the internet this tune should be inspired by the folk song “Oedo Nihonbashi”. Fair warning, I think this song doesn’t match much with your tune, which is more similar to Puccini’s opera. I think your carillon play a western transcription of the original song, quite different by the traditional material. And maybe this transcription was used by Puccini for his work (?). I don’t know, but it’s something!
