| It is usually related to audio in music, as the effect can be perceived only if the waveform has tonal qualities. The effect is described as "thick," "rich," adding subtle tonal movement, "shimmering quality" and "dreaminess" to a sound, making the impression that it is doubled in quantity. <ref name="testtone1">{{cite TestTone.com|url="http://testtone.com/fundamentals/what-chorus-effect"|title="What is a Chorus Effect?"}}</ref> | |
| In most cases, the processed effect is associated with vocals, [[electric guitar|electric guitars]], [[bass guitar|basses]] and electric pianos while it can be heard naturally in choirs, synthesizers, mandolins, accordions, string and brass ensembles, acoustic [[twelve-string guitar|twelve-string guitars]] and out-of-tune acoustic pianos due to microtonal differences between individual instruments or sound sources. | |
