How to fit a vocal to a beat's key

A vocal in the right key sounds like it was recorded on that beat. Here is how to check, and what to do when it is not.

Check for a match first

Look up the vocal's key. A beat in the same key fits, and so does one in its relative key, which uses the same notes: C major and A minor, for example.

Move the beat if you can

Moving the beat up or down a semitone or two is nearly always cleaner than moving the voice, because people notice a changed voice first.

If the voice has to move

Use a pitch shift that keeps the formants, so the voice keeps its own character. A semitone or two usually holds up, and past that it starts to sound like someone else.
