[ Yeah, Strange had a feeling it did. Hopefully this analogy will make it better (though he has a feeling it's only going to cause Lambert to give him all the more questions). ]

Music's written note for note, tone for tone. [ And Strange hums a few bars of some sort of old folk song. He hums them in a very measured fashion, like he's reading the notes directly off a sheet of paper. Thankfully, he stays on key, but it's obvious just from the humming that Strange isn't going to win any awards for his singing. ] But nobody performs music like that. You put yourself in the song and change it up a bit. [ And so, Strange hums the same few bars again, but the tempo's changed a little, a few of the notes are longer and shorter, it's Strange having a bit more fun with the piece and humming it like people might actually sing it. ]

That's what you need to do with your magic. It seems a bit too straightforward. I know you'll say that witchers aren't meant for this or whatever excuse you've used before, but at least try to explore it a little.
