I also believe it's about Triton and Ursula. I think Ursula was a mermaid once (mermaids have a lovely singing voices, right?) and maybe she was cursed by Triton or something like that (I remember King was supposed to be shady and very protective of his family). After all, 'evil isn't born, it's made' and it could be the reason Ursula become villain.
