If there's one thing Chara is good at, it's memorising things, even if sometimes they can't trust their own ability to. The pattern is easily copied without hesitation or flaw, and added to in turn, with the minutest pause before three more notes are sounded out, adding the black keys in.

The feeling of a number going up.
