Quick one, this song is in the key of E flat major, an e natural comes up, i play it unflatted, but then another E came out without an accidental, is that a natural or a flat? if its a natural, does taht mean that even for flats and sharps, if the E before another E were to be a sharp/flat, and another E is shown without accidentals, its played as a sharp / flat??
The E will remain E natural for the rest of the measure. The measure line will cancel out the accidental and the arranger or whatever will notate a natural sign after that if thats what he wants.
