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

They make the same note. That note has different names depending on context. Primarily it depends on the key you are in and if the musical line is going up or down.
