Plainsong developed during the earliest centuries of Christianity, influenced possibly by the music of the Jewish synagogue and certainly by the Greek modal system. It has [[Neume|its own system of notation]].<ref name="weber" />

As the number of chants in the church's repertoire increased, officials needed a better way to standardize the music.<ref name=":0" /> A unique form of musical notation was developed to help standardize the music and provide a reference for the performers and audience alike.<ref name=":1" /> The musical notations that were used were called [[neume]]s, and they are employed on a four-line staff, unlike the five-line staff we are accustomed to today.<ref name=":0" /> The neumes are placed above the chant's words to help the performer identify the piece's melody but did not specify the pitches or intervals that needed to be sung.<ref name=":1" /> Even though there were written musical manuscripts, the performers still needed to memorize the chants through oral traditions before interpreting the notation.<ref name=":1" /> It was not until the eleventh century that musical pitches were being integrated into written music.<ref name=":1" />

Most of the early plainsong scripts have been destroyed due to war, purposeful destruction and natural causes such as water, fire, and poor environmental conditions.<ref name=":1" /> The Toledo Cathedral in Spain has one of the world's largest collections of indigenous plainsong manuscripts devoted to Western Christianity.<ref name=":3">{{Cite journal|last1=Noone|first1=Michael J.

There are three methods of singing psalms or other chants, [[responsory|responsorial]], [[antiphon|antiphonal]], and solo.<ref name=":1" /> In responsorial singing, the soloist (or choir) sings a series of verses, each one followed by a response from the choir (or congregation). In antiphonal singing, the verses are sung alternately by soloist and choir, or by choir and congregation.<ref name=weber>[http://www.liturgica.com/html/litWLMusDev1.jsp Weber, Jerome F. "Early Western Chant", Western Catholic Liturgics] {{webarchive|url=https://web.archive.org/web/20131024132500/http://liturgica.com/html/litWLMusDev1.jsp |date=2013-10-24 }}</ref> It is probable that even in the early period the two methods caused the differentiation in the style of musical composition which is observed throughout the later history of plain chant, the choral compositions being of a simple kind, the solo compositions more elaborate, using a more extended compass of melodies and longer groups of notes on single syllables. The last type of plainsong performance is the solo performed by the choir or the individual performer.<ref name=":1" /> A marked feature in plainchant is the use of the same melody for various texts. This is quite typical for the ordinary psalmody in which the same formula, the "psalm tone", is used for all the verses of a psalm, just as in a hymn or a folk song the same melody is used for the various stanzas.<ref name=":2" />

[[Gregorian chant]] is a variety of plainsong named after [[Pope Gregory I]] (6th century AD), but Gregory did not invent the chant. The tradition linking Gregory I to the development of the chant seems to rest on a possibly mistaken identification of a certain "Gregorius", probably [[Pope Gregory II]], with his more famous predecessor. The term Gregorian Chant is often incorrectly used as a synonym of plainsong.<ref name=":1" />

For several centuries, different plainchant styles existed concurrently. Standardization on Gregorian chant was not completed, even in Italy, until the 12th century. Plainchant represents the first revival of [[musical notation]] after knowledge of the ancient Greek system was lost.

In the late 9th century, plainsong began to evolve into [[organum]], which led to the development of [[polyphony]]. When polyphony reached its climax in the sixteenth century, the use of plainsong chant was less appealing and almost completely abandoned.<ref name=":2" />

There was a significant plainsong revival in the 19th century, when much work was done to restore the correct notation and performance-style of the old plainsong collections, notably by the monks of [[Solesmes Abbey]], in northern France. After the [[Second Vatican Council]] and the introduction of the vernacular Mass, use of plainsong in the Catholic Church declined and was mostly confined to the [[Monasticism|monastic orders]]<ref name=":2" /> and to ecclesiastical societies celebrating the traditional Latin Mass (also called ''Tridentine Mass''). Since [[Pope Benedict XVI]]'s ''motu proprio'', ''[[Summorum Pontificum]]'', use of the Tridentine rite has increased; this, along with other papal comments on the use of appropriate liturgical music, is promoting a new plainsong revival.<ref>{{Cite web|url=http://catholicherald.co.uk/commentandblogs/2017/07/07/on-the-tenth-anniversary-of-summorum-pontificum-we-can-safely-say-the-doomsayers-are-wrong/|title=On the 10th anniversary of Summorum Pontificum, we can safely say the doomsayers are wrong|last=Reid|first=A.|date=2016|website=Catholic Herald}}</ref><ref>{{Cite web|url=https://www.vatican.va/content/benedict-xvi/en/letters/2007/documents/hf_ben-xvi_let_20070707_lettera-vescovi.html|title=LETTER OF HIS HOLINESS BENEDICT XVI TO THE BISHOPS ON THE OCCASION OF THE PUBLICATION OF THE APOSTOLIC LETTER "MOTU PROPRIO DATA" SUMMORUM PONTIFICUM ON THE USE OF THE ROMAN LITURGY PRIOR TO THE REFORM OF 1970|last=BENEDICT XVI|date=2007|website=LA SANTA SEDE}}</ref>

The [[Plainsong and Medieval Music Society]] was founded in 1888 to promote the performance and study of liturgical chant and medieval polyphony.<ref name=":2" />

Interest in plainsong picked up in 1950s Britain, particularly in the left-wing religious and musical groups associated with [[Gustav Holst]] and the writer [[George B. Chambers]]. In the late 1980s, plainchant achieved a certain vogue as music for relaxation, and several recordings of plainchant became "classical-chart hits".
