Legend notes on the piano?

What are legend notes on the piano?? my friend told the that they are the ones that I cant read or understand or something...so what are they??

Are you perhaps talking about ledger notes?

Music notes above or below the staff are placed on ledger lines and are refered to as ledger notes.

yep I think thts it lol sorry!! so does anyone know what ledger nots are?? lol

Are you learning to read music? Do you see where the middle C is written? It's below the stave on a line of its own. That's an example of a ledger note - one that falls outside the stave, or staff.
