is a stringed instrument
technique performed by plucking a string by "pulling" the string off the fingerboard
with one of the fingers being used to fret the note.
A pull-off is often performed on a string which is already vibrating; when the fretting finger is pulled off (exposing the string either as open or as stopped by another fretting finger lower on the same string) the note playing on the string changes to the new, longer vibrating length of the string. Pull-offs are performed on on both fretted instruments (e.g., electric guitar) and unfretted instruments (e.g., violin). They are used to sound gracenotes
, in part because since the string is not picked or bowed again to produce the sound of the second note, the transition from one to the other sounds gentler and less percussive.
In the transition between the initial and final notes, the string may vibrate in an inharmonic manner for several cycles when it is plucked with the fretting finger, because the string is being plucked in a part of the string not usually used for plucking . The result,a slight "quack" sound, may be particularly audible when the interval of the pull-off is large . This transition also consumes some of the vibrational energy in the sounded string, with the effect that the second note is generally much quieter than the original.
Acoustic versus electric instruments
On most acoustic instruments, this means the second note has little sustain
. As a result, in acoustic music, pull-offs are primarily used as an embellishment. Performers of plucked instruments tend to use "pull-offs" when playing grace notes, usually in conjunction with multiple hammer-ons
and strumming or picking to produce a rapid, rippling effect. In rock
and heavy metal music
, electric guitars
are often performed with overdriven amplifiers and/or guitar effects
such as distortion pedals
pedals are used, which add substantial sustain to the sound. With this type of electronic gear and a powerful instrument amplifier
nearing the threshold of feedback
, pull-offs can even be used to play sustained notes.
In a variation of the technique, often called a "flick-off", the pulling-off finger is dragged slightly across the face of the string while performing the pull-off. This results in the string being gently sounded, either by the player's finger callus or by their fretting-finger fingernail. This increases the volume and sustain of the pulled-off note, although the sound of the fretting finger dragging over the string may be audible on both an amplified instrument and on a brightly-strung acoustic instrument.
Classical music of the late romantic
period features numerous applications of the technique to bowed string instruments such as the violin, viola, cello, and double bass. In the classical context, the term is referred to as left-handed pizzicato
. When a player switches from arco (bowing) to regular pizzicato, they normally require a short pause to switch their bowing hand into pizzicato position and pluck the string. With left-hand pizzicato, though, a string player can play a pizzicato note immediately following a bowed note. It is used in violin
"virtuoso pieces" such as Pablo de Sarasate
and Paganini's 24th Caprice
as a way of interspersing open string pizzicato notes into rapid passages of bowed notes.
