Question…

I have a vocal I’m trying to use in a remix that is in Bb minor but I’m struggling to get the vibe I want in this scale, if I can find the notes she sings could I work in a different scale, provided they share the same notes? Anyone ever tried this?

You can have a look aroud whether you can find the sheet music for that vocal you are using.br
Otherwize you’ll have to do it by ear.br

If you know the scale of the vocal already you can change the key by transposing in semi-tones. This would change the key of the vocal, obviously there are certain restrictions in that you would want to change it by more than 2 semi tones or so.
