I know the symbols for sharp and naturals, but im a bit confused on something relating to them. F is sharp in the key sig, so I know all of them will be played sharp. When I see a natural sign before an F in one of the bars or measures. I know this means to play that note as an F instead of F#, What Im not quite sure of is, if It cancels out all the F# in that bar/measure or if I just play that one note as F. Also Im seing # symbols after the key signature, but before certain notes. (like C) I know that means to play that particular note sharp. Then ill see the same thing a few notes, or even bars down the staff. What the heck do I do in there, Im thinking Im supposed to play all C notes sharp untill I reach the next sharp symbol and once i reach that all C notes should be played normal and not sharp. quick example and a crude one at that. starting with 4 E and Ah on bar one, then begining with 1 E and ah on bar 2, b...d....#c....b..| #c....g.....a....g Sorry if this sounds confusing, but I am confused about this.
