flat sign
sharp sign
natural sign
and umm....idk what the common piano majors are
but to tell look in the key signature (beginning of each line where the clef is)
sometimes they'll be like 2 # signs and sometimes there'll be like none
in the mario song there's none so it's a C major
if there's 1 # it's G major and you would have to sharp all the F's in the song
if there's 2# it's D major and you would have to sharp all the F's and C's in the song
those are the common one's for violin so yea
never knew music was so confusing till now
