In western music, notes are assigned alphabetic names (A, B, C etc...) which are separated in pitch by certain frequencies. The standard frequency division is the tone. Tones can be further divided into semitones, which have the value of half a tone. When written out as score each tone is assigned a vertical position (on a line or in a space) on the stave:

Because the lines on the stave only distinguish between tones, notes are modified by the use of accidentals. The two main accidentals are sharps and flats; these respectively raise or lower the pitch of a note by a semitone. Double flats and double sharps can change the frequency of a note by less than a semitone.
