(The Fat Lady is singing, trying to break a glass with her voice…)

Seamus Finnigan: She just won’t let me in.

Harry Potter: Fortuna Major.

Fat Lady: No, no, no. Wait, wait. Watch this. (Her singing turns to screaming, the glass isn’t cracking so she smashes it against the wall) Amazing. Just with my voice.
