PLAINCHANT (also plainsong; Latin: cantus planus) is a body of chants used in the liturgies of the Western Church.
Plainsong is monophonic, consisting of a single, unaccompanied melodic line. Its rhythm is generally freer than the metered rhythm of later Western music.
An ANTIPHON (Greek ἀντίφωνον, ἀντί "opposite" and φωνή "voice") in Christian music and ritual is a responsory by a choir or congregation, usually in the form of a Gregorian chant, to a psalm or other text in a religious service or musical work.
According to Grout, a TROPE was originally a newly composed addition, usually in neumatic style and with a poetic text, to one of the antiphonal Chants of the Proper of the Mass (most often to the Introit, less often to the Offertory and Communion); later, such additions were made also to Chants of the Ordinary (especially the Gloria). The earliest tropes served as prefaces to the regular chant; at a later stage, tropes are found also in the form of interpolations between the lines of a chant.
In the early manuscripts of chants are to be found from time to time certain rather long melodic passages which recur, practically unchanged in many different contexts.
Long melismas of this sort came to be attached to the Alleluia in the liturgy -- at first simply as extensions of the chant but later, in still larger and more elaborate forms, as new additions. Such extensions and additions were given the name sequentia or "SEQUENCE" (from the Latin "siquor," to follow), perhaps originally because of their position "following" the Alleluia.
