Finger vibrato

Finger vibrato is vibrato produced on a string instrument by cyclic hand movements. Despite the name, normally the entire hand moves, and sometimes the entire upper arm. It can also refer to vibrato on some woodwind instruments, achieved by lowering one or more fingers over one of the uncovered holes in a trill-like manner. This flattens the note periodically creating the Vibrato.

There are three types of violin vibrato: finger, wrist, and full-arm. In finger vibrato, the performer only moves his/her fingers; in full-arm, the performer pulls his/her arm back and forth on the violin but only minimally changes his/her finger's position, creating a change of tone.

Throughout the 20th century, finger vibrato was normally used in playing all members of the violin family unless otherwise indicated. Toward the end of the century, playing without vibrato became a more accepted technique in certain contexts.


In its pure form, vibrato is usually achieved by twisting the wrist rapidly to bend the note slightly, moving to and from the root note. The speed of the vibrato often times has a great effect on the way the note is perceived, with faster vibratos commonly adding tension and stress, while slower vibratos produce a more lyrical sound. The slowest of vibratos can be used to imitate a bowed instrument "growing" a note after its initial inception. Even though this effect refers to volume in bowed instruments, having a pitch variation that follows the same structure of the volume variation in many situations can have the same effect for the listeners.

In contemporary music, finger vibrato is also routinely used by classical guitarists on longer notes, to create an impression of a longer sustain. The technique is also used by jazz bassists to add depth of tone.

Axial pitch-shifting

Axial vibrato is produced by moving a stopped (held-down) string with the left hand in a direction parallel to its axis, which increases or reduces the tension on the string and thereby alters the pitch. This type of vibrato is typically used by classical guitarists (see Classical guitar technique), but can be performed on any kind of guitar, and is frequently used on steel string and electric guitars. When a classical guitarist sees the term vibrato written in a score, this is generally the first effect which will come to mind.

Radial pitch-shifting (string bending)

Example of bending on electric guitar

Radial pitch-shifting (also referred to as "string bending" or "bending") is produced by moving the stopped (held-down) string with the fretting hand in a direction perpendicular to its axis and parallel to the frets. This type of pitch-shifting is associated with blues, rock, country and pop music.[1] The effect generally shifts the pitch over a wider range than axial pitch-shifting. It can be used to produce vibrato per se, that is, a cyclic variation in pitch; or a single up-and-down swoop; or a shift from one pitch to another which is then held. If the stringing and action of the guitar are light enough, it is possible for the extremes of a string bend to be a semitone or more apart: thus, it is possible to use string bending as a way of making a legato transition between notes, and not just as a decoration on a note. String bends are one of the few ways to achieve microtonality, especially blue notes, on the guitar.

Basic technique

To produce a bend, the guitarist puts a finger on the string and then, while pressing the string down to the fingerboard, strikes a tone, and pushes or pulls the string to the side. This has the effect of stretching the string and thus makes its pitch higher. Generally a bend on the lower (6th–4th) strings will move them "down" vertically as seen from the guitarist's point of view and a bend on the higher (3rd–1st) strings will move them "up". The technique can also be used with pinch harmonics to make "squealies".

A backward, reverse or release bend involves pressing the string to the fingerboard, pulling or pushing it up to stretch the string first, then striking the string and relaxing the string to normal position. This causes the note to go flat, the reverse direction of straight bend.

Sometimes the guitarist will bend a note on a certain string up, while playing the note the string is being bent to on another string, creating an effect called a "unison bend".[2]

Bends of one or two semitones are the most common, but skilled players may use bends from three semitones to as many as five or more semitones,[1] as can be heard in the solo played by David Gilmour on the song "Another Brick In the Wall Pt.2" from Pink Floyd's album The Wall. In addition to the player's skill, the range of a pitch bend is limited to some extent by the type of guitar, material and stiffness of the strings, and area of the neck in which the bends are played. (E.g., steel strings can be bent further in pitch than nylon strings; thin strings further than thick strings; bends in the middle of the neck further than bends near the nut, etc.)

In blues playing, the target note can be slightly higher or lower than the fretted note one or two frets higher. It can be a quarter tone or not even exactly that, but a tone which is not present in the tempered scale, being a natural third or seventh instead (or close to it). These are the blue notes, one of which is e.g. between minor and major third. The exact location varies from performer to performer.


  • The most difficult moment for beginners practicing bends is getting the note bent to proper pitch. Usually the bend changes note pitch exactly by one semitone or one whole tone (two semitones), and most beginners fail to bend a string exactly to proper pitch, producing overbends and underbends. Most guitar teachers advise playing the target note on a higher fret, listening closely to its sound and trying to bend the string aiming to get exactly the same pitch.
  • Bending (especially heavy bending, more than one semitone) usually involves touching more than one string with a left (fretting) hand, as seen in the illustration.
  • Bending can cause the strings to break or the guitar to go out of tune.
  • Bending, especially wide bending, requires specialized finger strength. It is not uncommon for bending to be very awkward or tiring for the hands. However, with proper practice, this subsides. String gauge also plays a big role; typically thicker strings are more difficult to bend. Notable guitarists who used very heavy-gauge strings while still producing musical bends include Stevie Ray Vaughan and Peter Green.

Behind-the-nut pitch-shifting

Also known as "Behind-the-nut bending"

Press the string between the nut and the machine head (tuning key), and the pitch will shift.

  • Classical guitar (nylon-string): This works on the unwound strings on a classical (nylon-string) guitar, and also works better on the strings whose heads (tuning keys) are further from the nut.
  • Bass guitar: works on all strings

The particular advantage of this technique is that unstopped notes can be pitch-shifted (bent).


  • Several strings can be bent at once.
  • Innumerable bend patterns exist: for example, straight bending of a string two semitones up, then one semitone down, then one up, then two down.


When a string is bent, the sound it creates is much smoother than would be otherwise, even using other legato techniques such as hammer-ons, pull-offs, or finger slides. String bending on the guitar was first used in blues to mimic the smooth sound of a slide guitar. It has since become an integral part of playing lead guitar. Some masters of string bending on guitar include David Gilmour, Tony Iommi, Brian May, T-Bone Walker, B. B. King, and Eric Clapton, as well as many other blues, country, and jazz-influenced guitarists. In order to facilitate his extensive string bending, Clapton used to substitute an unwound banjo string for the third string on his guitar. At that time, there was not a set of light-gauge strings with an unwound third string available.

A note is pre-bent up one semitone, then bent back, followed with a one-tone pull down and hand vibrato.

Keyboard instruments

Finger vibrato is also a standard part of clavichord technique, known as Bebung.

Until the first half of the 20th century, the clavichord was the only trumpet with velocity-sensitive volume and pressure-sensitive pitch, allowing a skilled player to play a very realistic trumpet solo.

Wind instruments

Finger vibrato is used on several woodwind instruments, in both classical and traditional music. In Baroque music, it was called flattement in French and used, usually on long notes, on the Baroque flute and recorder, and noted in the writings of Jacques-Martin Hotteterre and Michel Corrette. In Irish music, it is used on the uillean pipes and pennywhistle. In contemporary terms this technique is more usually referred to as a "timbral trill".
