Why do black keys on a piano have 2 names?

Question

I’m a complete novice to music and am learning piano, I just bought some stickers with the notes and letters for my keys but the black keys have 2 notes and letters, do they make a different sound when you hit them higher up vs lower on the key?

Answer 1

You’re referring to sharp (#) and flat (b). Its the same note. Think of it as halfway between two natural notes. A# (sharp) is the same as B b(flat)
