Editing Wah-wah (music) (section)

==Technique==
The method of production varies from one type of instrument to another. On brass instruments, it is usually created by means of a [[Mute (music)|mute]], particularly with the harmon (also called a "wa-wa" mute) or plunger mute. Woodwind instruments may use "[[Fingering (music)#Woodwind instruments|false fingerings]]" to produce the effect.

Any electrified instrument may use an auxiliary [[Signal processing|signal-processing]] device, or pedal. Often it is controlled by movement of the player's foot on a rocking pedal connected to a [[potentiometer]]. An alternative to players directly controlling the amount of effect is an '[[auto-wah]]'. These devices, usually make harder hit notes more trembly with a more prominent wah wah effect.{{sfn|Hunter|2004}} Wah-wah effects are often used for soloing or for creating a "wacka-wacka" [[funk]] rhythm on guitar.{{sfn|Du Noyer|2003|loc=375}} Although these electronic means are most often on electric guitar, they are also often used on [[electric piano]].{{sfn|Kernfeld|2002}}
