[TOMT] A popular opera song sung by a woman

Hi there, this song randomly came into my mind and I can’t figure out what it’s called. It’s an opera song and I remember watching YouTube shorts of multiple singers performing it. I think it’s famously difficult to sing.. so please excuse my attempt. Thank you.

Here’s the vocaroo link of me trying to recreate it: https://voca.ro/1fpyaa9qOAtg
