A muted or dampenednotes that has rhythm but often no discernible pitch. It is often thought of as an implied note in a musicalphrase and can be not performed or performed only faintly for effect. The use of this effect with the electric guitar and bass guitar is a more aggressive sound than with the wind instruments, but the effect still is a rhythmic pulse without a discernible pitch. The false note is indicated by a (parenthesis) around the notehead or with an "X" in place of the notehead, indicating that the note is to be played very quietly, as a ghost.
