Or, if written in 4 flats, it might be raised a semitone by 
being played as if written in 3 sharps, without needing to alter 
the score (except in any accidental sharps or flats it contains). 
Often, in instrumental playing, sharp keys may be easier than 
flat ones, or vice versa , and an immediate change can thus be 
effected ; or in singing, the voice may want a little easing in 
pitch, which is thus easily given. 
These results we have arrived at from the useful succession of 
fifths will, it is hoped, clear the way in sundry difficulties of 
home music, adding to its easy understanding and so to its 
pleasure.
