<P> The convention for the notation of key signatures follows the circle of fifths . Starting from C major ( or equivalently A minor ) which has no sharps or flats , successively raising the key by a fifth adds a sharp , going clockwise round the circle of fifths . The new sharp is placed on the new key 's leading note ( seventh degree ) for major keys or supertonic ( second degree ) for minor keys . Thus G major ( E minor ) has one sharp which is on the F ; then D major ( B minor ) has two sharps on F and C and so on . </P>
