guitar
The guitar is a fretted musical instrument that typically has six strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected string ...

Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. From a physics standpoint, there is no distinction between noise and desired sound, as both are vibrations through a medium, such as air or water. The difference aris ...

shifting on one string, or changing from one string to another.
String noise is often an unwanted side-effect that musicians try to avoid or minimize, especially when playing with amplification or
distortion
In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio s ...

An electric guitar is a guitar that requires external amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar (however combinations of the two - a semi-acoustic guitar and an electric acoustic gu ...
). However, string noise can be intentionally used or emphasized as a
stylistic choice.
String noise is generally relatively quiet but parallel string motion brings out higher, more dissonant harmonics than perpendicular string motion. However this should not be confused with parallel rather than perpendicular bowing, which is relatively quite loud and harsh.
If the pressure was consistent then the result would be a
glissando
In music, a glissando (; plural: ''glissandi'', abbreviated ''gliss.'') is a glide from one pitch to another (). It is an Italianized musical term derived from the French ''glisser'', "to glide". In some contexts, it is distinguished from the ...
. However, if the pressure is eliminated, then string noise does not result but the movement is more difficult. On fretted string instruments, the frets guide the movement of the hand, making the movement easier, but the frets increase the amount of contact, making fret noise more difficult to avoid.
