Chorus

Definition

A modulation effect that creates the impression of multiple instruments or voices by layering slightly pitch-shifted and time-delayed copies of the original signal.

In Simple Terms

An effect that makes one instrument sound like several are playing together. Subtle use thickens a guitar or synth; heavy use creates a dreamy, underwater shimmer.
