The rules for sharps ( # ), flats ( v ), naturals ( F ), double sharps ( ӿ ), and
double flats ( vv ) are:
1 ) A natural cancels a sharp or flat.
2 ) A single sharp or flat cancels a double sharp or double flat
respectively.
3 ) One natural alone cancels both double sharps and double flats.
4 ) An accidental remains in effect for the duration of the measure it is
in, or for the duration of tied pitches, inside a measure or across the
bar line
5 ) To raise a note which has previously been sharped, use a double
sharp; to lower a note which has been flatted, use a double flat.
6 ) An accidental only affects a specific note in that octave, in that clef.
All other notes of the same name are not affected.
