The following six keys ( which are the parallel major\/minor keys of those above ) would require one , two or three double-sharps or double-flats : For example , pieces in the major mode commonly modulate up a fifth to the dominant ; for a key with sharps in the signature this leads to a key whose key signature has an additional sharp .
The following six keys ( which are the parallel major\/minor keys of those above ) would require one , two or three double-sharps or double-flats : For example , if a piece in E major were to modulate up a fifth to B major , which is next to it on the circle and on the same side of the circle , the notation is clear and simple ; an extra sharp is added to make five sharps .
