<P> In music, a ghost note is a musical note with a rhythmic value, but no discernible pitch when played . In musical notation, this is represented by an "X" for a note head instead of an oval, or parentheses around the note head . It should not be confused with the X-shaped notation that raises a note to a double sharp . </P> <P> On stringed instruments, this is played by sounding a muted string . "Muted to the point where it is more percussive sounding than obvious and clear in pitch . There is a pitch, to be sure, but its musical value is more rhythmic than melodic or harmonic...they add momentum and drive to any bass line ." Occurring in a rhythmic figure they are purposely deemphasized, often to the point of near silence . In popular music drumming these notes are played, "very softly between the' main' notes," (off the beat on the sixteenth notes) most often on the snare drum in a drum kit . Ghost notes are often used by electric bass players and double bass players in a range of popular music and traditional music styles . In vocal music it represents words that are spoken in rhythm rather than sung . </P>
