Bowing on the bridge

Bridge (instrument)

 produces two different effects depending on how it is done. If it is done while the performer is in normal playing position, the sound produced is quiet, whispery and a bit squeaky. This method could more properly be called 'bowing over the bridge', since the bow hair is usually still in contact with the strings. Sul ponticello (bowing near the
bridge) is a similar, more common technique.

The other method involves the performer holding the instrument in their lap, placing the bow parallel to the instrument and firmly dragging it across the side of the bridge. In this case the sound is loud, high pitched and squeaky. An example of this playing technique can be found in Gérard Grisey’s
Gérard Grisey
Gérard Grisey was a French composer of contemporary music.-Biography:Gérard Grisey was born in Belfort, France on 17 June 1946. He studied at the Trossingen Conservatory in Germany from 1963 to 1965 before entering the Conservatoire de Paris...

 creates a very quiet resonant sound. Because the tailpiece is large and heavy this sound is general of a quite low pitch.

Scratch tone

A scratch tone is produced by bowing the instrument in normal playing position, but applying very hard pressure to the bow. This produces an extremely loud and grating sound.

Bowing behind the bridge

This fairly common extended technique involves bowing the instrument on the short length of string behind the bridge. The tone is very high and squeaky. 3rd Bridge

 was the first to direct its use.) The technique consists of plucking the string away from the fingerboard with the right hand with sufficient force to cause it to snap back and strike the fingerboard creating a snapping sound in addition to the pitch itself.

Nail Pizzicato

Nail pizzicato is another technique invented and used extensively by Bartók. To perform a nail pizzicato, the performer plucks the string with only the fingernail (in standard string performance technique the player uses the pad of the finger). The resulting sound is a bit more harsh and metallic.

"Silent" fingering

A performer can stop the strings with his left hand in an unusually forceful maneuver and thereby produce a percussive effect. Although quiet, the name “silent” is a misnomer and refers to the fact that the bow is often not applied when performing this effect.

Striking the Strings

The strings

 can be struck with the hand or with another object to produce a loud ringing or percussive sound. The performers right hand is often used for this which leaves the left hand free to finger pitches or dampen the strings.

Tapping on the instrument

String instruments can be tapped just about anywhere. The body of a string instrument, being a resonant cavity, can resound quite loudly when struck with the fingers or another object.

“Chewing”

An effect sometimes used for humorous effect by string players, “chewing” is performed by loosening the bow hair and placing the bow, bow hair side up, against the back of the instrument. The bow is then rotated causing the bow stick to pop and crunch as it goes over the coarse bow hairs. This effect, which sounds remarkably like a person chewing something crunchy, is fairly quiet and could benefit from amplification.

Bow screw glissando

The bow can be held vertically and the screw of the bow placed firmly against a string either at the location of a fingered note or at some other point. The string can then be plucked with the right hand and the screw of the bow can be simultaneously dragged up or down the string. The effect of this is to produce a quiet rising or falling ping. This effect is used in Helmut Lachenmann’s
