Plainsong or plainchant is a body of chants used in the liturgies of the Western Church. When referring to the term plainsong, it is those sacred pieces that are composed in Latin text. Plainsong was the exclusive form of Christian church music until the ninth century, and the introduction of polyphony.
An antiphon is a short chant in Christian ritual, sung as a refrain. The texts of antiphons are the Psalms. Their form was favored by St Ambrose and they feature prominently in Ambrosian chant, but they are used widely in Gregorian chant as well. They may be used during Mass, for the Introit, the Offertory or the Communion. They may also be used in the Liturgy of the Hours, typically for Lauds or Vespers.
Gregorian chant is the central tradition of Western plainchant, a form of monophonic, unaccompanied sacred song in Latin of the Roman Catholic Church. Gregorian chant developed mainly in western and central Europe during the 9th and 10th centuries, with later additions and redactions. Although popular legend credits Pope Gregory I with inventing Gregorian chant, scholars believe that it arose from a later Carolingian synthesis of the Old Roman chant and Gallican chant.
Petr Eben was a Czech composer of modern and contemporary classical music, and an organist and choirmaster.
The Magnus Liber or Magnus liber organi, written in Latin, was a repertory of medieval music known as organum. This collection of organum survives today in three major manuscripts. This repertoire was in use by the Notre-Dame school composers working in Paris around the end of the twelfth and beginning of the thirteenth centuries, though it is well agreed upon by scholars that Leonin contributed a bulk of the organum in the repertoire. This large body of repertoire is known from references to a "magnum volumen" by Johannes de Garlandia and to a "Magnus liber organi de graduali et antiphonario pro servitio divino" by the English music theorist known as Anonymous IV. Today it is known only from later manuscripts containing compositions named in Anonymous IV's description. The Magnus Liber is regarded as one of the earliest collections of polyphony.
The Winchester Troper refers to two eleventh-century manuscripts of liturgical plainchant and two-voice polyphony copied and used in the Old Minster at Winchester Cathedral in Hampshire, England. The manuscripts are now held at Cambridge, Corpus Christi College 473 and Oxford, Bodleian Library Bodley 775 . The term "Winchester Troper" is best understood as the repertory of music contained in the two manuscripts. Both manuscripts contain a variety of liturgical genres, including Proper and Ordinary chants for both the Mass and the Divine Office. Many of the chants can also be found in other English and Northern French tropers, graduals, and antiphoners. However, some chants are unique to Winchester, including those for local saints such as St. Æthelwold and St. Swithun, who were influential Bishops of Winchester in the previous centuries. Corpus 473 contains the most significant and largest surviving collection of eleventh-century organum. This polyphonic repertoire is unique to that manuscript.

Ambrosian chant is the liturgical plainchant repertory of the Ambrosian rite of the Roman Catholic Church, related to but distinct from Gregorian chant. It is primarily associated with the Archdiocese of Milan, and named after St. Ambrose much as Gregorian chant is named after Gregory the Great. It is the only surviving plainchant tradition besides the Gregorian to maintain the official sanction of the Roman Catholic Church.

The Choralis Constantinus is a collection of over 375 Gregorian chant-based polyphonic motets for the proper of the mass composed by Heinrich Isaac and his pupil Ludwig Senfl. The genesis of the collection is a commission by the Constance Cathedral for Isaac, at that time the official court composer for the Holy Roman Emperor Maximilian I, to compose a set of motets for the special holy days celebrated in the diocese of Constance. Isaac was in Constance at the time with the Imperial court as Maximilian had called a meeting of the German nobility (Reichstag) there. The music was delivered to the Constance Cathedral in late 1508 and early 1509.

The choir has played an important role as an interpreter and a proponent of Gregorian chant and sacred polyphony.
The Schola Cantorum was the trained papal choir during the Middle Ages, specializing in the performance of plainchant for the purpose of rendering the music in church. In the fourth century, Pope Sylvester I was said to have inaugurated the first Schola Cantorum, but it was Pope Gregory I who established the school on a firm basis and endowed it. The choir ranged anywhere from twenty to thirty boys or men. Only the most skilled in singing were selected to participate in the Schola Cantorum.
