Distortion is an audio effect that changes the sound by clipping or saturating the signal, creating a more aggressive, powerful and harmonically rich tone. It is widely used in rock, blues, metal and many modern keyboard sounds.
What is distortion?
Distortion occurs when an audio signal is driven beyond its clean operating range, causing the waveform to clip or saturate. Originally considered an unwanted by-product of overdriven tube amplifiers, distortion has become one of the most recognizable and expressive effects in modern music.
Different types of distortion—such as overdrive, distortion and fuzz—produce different amounts of saturation, sustain and harmonic coloration.
How is distortion used in piano playing?
Although distortion is most commonly associated with electric guitar, keyboard players also use it with electric pianos, synthesizers and organs to create more character and presence. A subtle amount of overdrive can help a keyboard cut through a dense band mix, while heavier distortion creates bold and dramatic textures.
Understanding how distortion affects tone allows piano players to shape expressive sounds for rock, blues, funk, gospel and contemporary worship music.
