CHORUS, in music, in its general sense, denotes a composition of two, three, four, or more parts, each of which is intended to be sung by a plurality of voices. Chorusses are made to follow a piece of music sung by one individual, or in parts by single or at least only a few voices, and, as it were, bring to a climax the joy, adoration, grief, or any other sentiment or passion therein expressed. The chorusses of Handel, particularly those in his oratorio of Messiah, are considered as the finest things of the kind that have ever been composed, and, when well performed with complete orchestral accompaniments, produce the most triumphant effect of which music is capable. Chorus is also applied to those who sing the parts.
