I'm learning this new piece and on one note it has a natural symbol for it but there was no symbol before it making it anything else other than a natural anyway.

Dunno why it's there, should I just play the white key anyway or does it mean something else?

Help will be appriciated, thanks.

im not musician but im guessing look at the Key signature? For example if its F Major which has B Flat in the Key signature, to make it B again for one note rather then just changing the whole key signature they would just put a natural sign on it?

Not sure if i made sense or anything but i hope this will help

True, also just like text books with spell check, it could just be an error-/ but if it doesn't affect the piece, Sibelius may not catch it
