Chorus is a widely utilized modulation effect that adds depth and movement to audio signals. It works by mixing a modulated version of the original sound with the dry signal, producing a rich and shimmering texture. This effect is popular among guitarists and keyboard players for its ability to enhance the sonic character of their instruments.

Originally prominent in the 1980s, chorus remains a staple in modern music production, valued for its capacity to thicken sounds and create a sense of spaciousness. By subtly shifting the pitch and timing of the duplicated signal, it generates a lush, layered effect that can transform simple melodies into more engaging and dynamic performances.

Chorus can be applied across various musical genres to enrich tone and add expressive nuances. Its straightforward yet impactful nature makes it an essential tool in both live and studio settings, helping musicians and producers achieve a fuller, more immersive sound.
