Hello, I’ve just recently seen an episode of an old-ish TV show called “Beauty and the Beast”. It’s more like a stage production was filmed than a television series, but the music is very pretty and romantic.
If you mean the TV show with Linda Hamilton and Ron Perlman, the theme music is “The First Time I Loved Forever.” It was published as piano sheet music. There is a little tricky pedaling but it is playable on harp pretty much as written.
