Musical note indicated by placing the symbols in the key signature, which then apply implicitly to all occurrences of corresponding notes. Explicitly noted accidentals can be used to override this effect for the remainder of a bar. A special accidental, the natural symbol , is used to indicate an unmodified pitch. Effects of key signature and local accidentals do not accumulate. If the key signature indicates G, a local flat before a G makes it G (not G), though often this type of rare accidental is expressed as a natural, followed by a flat () to make this clear. Likewise (and more
Stopped note Stopped note On string instruments, a stopped note is a note whose pitch has been altered from the pitch of the open string by the player's left hand pressing (stopping) the string against the fingerboard. On bowed string instruments, a stopped note is a played note that is fingered with the left hand, i.e. not an open string. This assists with tone production, the addition of vibrato, and sometimes additional volume but creates difficulty in that bowed string instruments do not have frets, requiring ear training and accurate finger placement. The lack of frets, as on the guitar fretboard, does
