When did Gregorian chant first develop?

Gregorian chant is the central tradition of Western plainchant, a form of monophonic, unaccompanied sacred song 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 Roman chant and Gallican chant.

During the Lombard occupation of the 7th and 8th centuries, a distinctive liturgical rite and plainchant tradition developed in Benevento. It included feasts of special local importance such as the Holy Twelve Brothers of Benevento. At the time it was called "cantus ambrosianus" ("Ambrosian chant"), although it is a separate plainchant tradition from the chant of Milan which we call Ambrosian chant. The common use of the name "cantus ambrosianus", the common influence of the Lombards in both Benevento and Milan, and musical similarities between the two liturgies and chant traditions suggest a Lombard influence in the origins of Beneventan chant.
Gregorian chant had already begun to take hold in the Beneventan orbit as early as the 8th century. The two traditions appear to have coexisted for about a century before the Gregorian chant began to replace the native Beneventan. Many Beneventan chants exist only as interpolations and addenda in Gregorian chantbooks, sometimes next to their corresponding chants in the Gregorian repertory. External ecclesiastical influences, such as two German abbots at Montecassino during the 11th century, led to an increasing insistence on the Roman rite and Gregorian chant instead of the local Beneventan traditions. One of these abbots later became Pope Stephen IX, who in 1058 officially outlawed the Beneventan rite and chant. A few Beneventan chants continued to be recorded and performed for a time, especially for the feasts of local importance such as the Holy Twelve Brothers, which had no Gregorian counterpart. However, the Beneventan repertory as a whole fell into disuse. This was commemorated in a legend of a singing contest between a Gregorian and a Beneventan cantor, which ended in victory for the Gregorian repertory when the Beneventan cantor fainted from exhaustion.

Willi Apel and Robert Snow assert a scholarly consensus that Gregorian chant developed around 750 from a synthesis of Roman and Gallican chants, and was commissioned by the Carolingian rulers in France. Andreas Pfisterer and Peter Jeffery have shown that older melodic essentials from Roman chant are clear in the synthesized chant repertory. There were other developments as well. Chants were modified, influenced by local styles and Gallican chant, and fitted into the theory of the ancient Greek octoechos system of modes in a manner that created what later came to be known as the western system of the eight church modes. The Metz project also invented an innovative musical notation, using freeform neumes to show the shape of a remembered melody. This notation was further developed over time, culminating in the introduction of staff lines (attributed to Guido d'Arezzo) in the early 11th century, what we know today as plainchant notation. The whole body of Frankish-Roman Carolingian chant, augmented with new chants to complete the liturgical year, coalesced into a single body of chant that was called "Gregorian."

The first extant sources with musical notation were written around 930 (Graduale Laon). Before this, plainchant had been transmitted orally. Most scholars of Gregorian chant agree that the development of music notation assisted the dissemination of chant across Europe. The earlier notated manuscripts are primarily from Regensburg in Germany, St. Gall in Switzerland, Laon and St. Martial in France.

Between the 8th and 13th centuries, however, the Carolingian chant commissioned by Charlemagne developed into what we now know as Gregorian chant, which began to influence and eventually replace most of the other Western plainchant traditions. By the 12th century, the Mozarabic, Gallican, Celtic, Old Roman, and Beneventan chant traditions had all been effectively superseded by Gregorian chant. Ambrosian chant alone survived, despite the efforts of several Popes over a period of several centuries to establish Gregorian hegemony. A chronicle by the Milanese historian Landolphus from around the year 1000 recounts a legend that two Sacramentaries, one Gregorian and one Ambrosian, were placed on an altar to see which chant had divine acceptance; miraculously, both books opened simultaneously, showing both were equally acceptable.

Gregorian melodies provided musical material and served as models for tropes and liturgical dramas. Vernacular hymns such as "Christ ist erstanden" and "Nun bitten wir den Heiligen Geist" adapted original Gregorian melodies to translated texts. Secular tunes such as the popular Renaissance "In Nomine" were based on Gregorian melodies. Beginning with the improvised harmonizations of Gregorian chant known as organum, Gregorian chants became a driving force in medieval and Renaissance polyphony. Often, a Gregorian chant (sometimes in modified form) would be used as a "cantus firmus", so that the consecutive notes of the chant determined the harmonic progression. The Marian antiphons, especially "Alma Redemptoris Mater", were frequently arranged by Renaissance composers. The use of chant as a cantus firmus was the predominant practice until the Baroque period, when the stronger harmonic progressions made possible by an independent bass line became standard.

In 1925, Le Guennant arrived at the Gregorian Institute of Paris as director and teacher of Gregorian chant, succeeding Dom Joseph Gajard of the Solesmes Abbey.
After the Second World War, he organized many Gregorian sessions, not only in France but also in Fátima, and even Rio de Janeiro. Still teaching at the Gregorian Institute in Paris, this pedagogue and musician considerably boosted the teaching of Gregorian chant, by creating centres of study in several countries. When Maurice Duruflé thought about basing his Requiem on Gregorian chant, he asked Le Guennant for advice, and gratefully acknowledged his understanding. In 1960, Duruflé dedicated a composition to Le Guennant, his "Quatre Motets sur des thèmes grégoriens" which were also based on chant.

The monks of Solesmes, discussed above for their revival of Gregorian chant, issued a number of recordings. However, when Gregorian chant as plainchant experienced a popular resurgence during the new-age and world-music movements of the 1980s and '90s, the iconic album was somewhat unexpectedly "Chant", recorded by the Benedictine monks of Santo Domingo de Silos, Spain. This was marketed as music to inspire timeless calm and serenity. In 2008, the Cistercian Monks of Austrian Heiligenkreuz Abbey released the CD "Chant – Music for Paradise", which became the best-selling album of the Austrian pop charts and peaked #7 of the UK charts. In the US, the album was released under the title "Chant – Music for the Soul" and peaked at #4 on the Billboard classical charts.

Semiology (from Greek σημεῖον "sēmeion", "a sign, a mark") is a branch of Gregorian Chant research. Semiology refers specifically to the study of the neumes as found in the earliest fully notated manuscripts of Gregorian Chant, the oldest of which have been dated to the 9th century. The first application of the term 'semiology' (which first appeared in the 1960s) for the study of Latin chant was made by Dom Eugène Cardine (1905–1988), a monk of the Abbey of Solesmes. In this context, 'semiology' is understood as 'the study of musical signs'. Text and neumatic notation, together with significative letters adjoined to the neumes, presents an effective and integrated mnemonic for the rhythmical interpretation and the melody. While Gregorian palaeography offers a description of the various neumes and their rhythmical and melodic values, Gregorian semiology explains their meaning for practical interpretation.

Gregorian chant eventually replaced the local chant tradition of Rome itself, which is now known as Old Roman chant. In the 10th century, virtually no musical manuscripts were being notated in Italy. Instead, Roman Popes imported Gregorian chant from (German) Holy Roman Emperors during the 10th and 11th centuries. For example, the Credo was added to the Roman Rite at the behest of the Emperor Henry II in 1014. Reinforced by the legend of Pope Gregory, Gregorian chant was taken to be the authentic, original chant of Rome, a misconception that continues to this day. By the 12th and 13th centuries, Gregorian chant had supplanted or marginalized all the other Western plainchant traditions.
