How to find middle C on the piano

Black keys come in groups of two and three. Every C is the white key just to the left of a group of two black keys. Middle C (also called C4) is the C closest to the middle of the keyboard, usually right in front of you when you sit centred.

On a full 88-key piano the keys run from A0 at the bottom to C8 at the top. Smaller keyboards have fewer keys, but the pattern of two and three black keys is the same.
