Tonary
A tonary is a liturgical book in the Western Christian Church which lists by incipit various items of Gregorian chant according to the Gregorian mode of their melodies within the eight-mode system. Tonaries often include Office antiphons, the mode of which determines the recitation formula for the accompanying text, but a tonary may also or instead list responsories or Mass chants not associated with formulaic recitation. Although some tonaries are stand-alone works, they were frequently used as an appendix to other liturgical books such as antiphonaries, graduals, tropers, and prosers, and are often included in collections of musical treatises.
Function and form
Tonaries were particularly important as part of the written transmission of plainchant, although they already changed the oral chant transmission of Frankish cantors entirely before musical notation was used systematically in fully notated chant books. Since the Carolingian reform the ordering according to the Octoechos assisted the memorization of chant. The exact order was related to the elements of the "tetrachord of the finales" which were called "Protus, Deuterus, Tritus", and "Tetrardus". Each of them served as the finalis of two toni—the "authentic" and the "plagal" one. The eight tones were ordered in these pairs: "Autentus protus, Plagi Proti, Autentus Deuterus" etc. Since Hucbald of Saint-Amand the eight tones were simply numbered according to this order: Tonus I-VIII. [|Aquitanian cantors] usually used both names for each section.The earliest tonaries, written during the 8th century, were very short and simple without any visible reference to psalmody. Tonaries of the 9th century already ordered a huge repertoire of psalmodic chant into sections of psalmtone endings, even if their melody was not indicated or indicated by later added neumes. Most of the tonaries which have survived until now can be dated back to the 11th and 12th centuries, while some were written during later centuries, especially in Germany.
The treatise form usually served as a bridge between the Octoechos theory and the daily practice of prayer: memorizing and performing the liturgy as chant and reciting the psalms. This can be studied at a 10th-century treatise called Commemoratio brevis de tonis et psalmis modulandis, which used the Dasia-signs of the Musica enchiriadis treatise in order to transcribe the melodic endings or terminations of psalmody. 11th-century theorists like Guido of Arezzo or Hermann of Reichenau refused the Dasia tone system, because it displayed tetraphonic tone system and not the systema teleion which had all the pitches needed for the "melos of the echoi". Nevertheless, the first example of the eighth chapter in Musica enchiriadis, called "Quomodo ex quatuor Sonorum vi omnes toni producantur", already used the fifth of the Protus for an illustration, how alleluia melodies are developed by the use of the intonation formula for the "Autentus protus".
The different forms of a tonary
Tonaries can differ substantially in length and shape:- As a treatise they usually describe the octave, fifth and fourth species of each tone, but also their modal characteristics like microtonal shifts or the change to another melodic frame.
- It can also be an abridged form or breviary, which just show the sacramentary or antiphonary according to the liturgical year. The tonus of the antiphonal chant genres is indicated by later added rubrics as "ATe" for "Autentus Tetrardus" or the Roman Ordinals I-VIII according to Hucbald's system, as we can find it in the early Troper-Sequentiary of St. Géraud in Aurillac and the abridged Antiphonary of St. Martial.
- The most common form was the shortest one which had no theoretical explanation. Since the late 9th century each section started with an intonation formula and the psalmody of the mode, its pitches represented by letters or later by diastematic neume notation. Subsections followed the different chant genres quoted as examples for the represented tone. Antiphonal refrains in psalm recitation, usually represented by its text incipit, were sorted according to various terminations used in psalmody, the so-called "differentiae".
- A very rare form of tonary is a fully notated one, which shows every chant genre ordered according to its tonus. A very famous example is the full tonary for mass chant by Abbot William of Volpiano, written for his Abbey St. Benignus of Dijon.
The tonary's function in chant transmission
Michel Huglo developed in his dissertation the hypothesis about an original tonary which preceded the [|Metz tonary] and the tonary of St. Riquier. It was probably a coincidence that Pope Adrian I supported the Eastern Octoechos reform, but it is also evident that Carolingian diplomates present at the synode did not get interested in the communication of the modes by intonations called enechemata for the first time. Nevertheless, it was the difference between Greek and Latin chant sources, especially the particular function of the tonary in chant transmission, that led Peter Jeffery to the conclusion that the huge repertoire of Roman chant was classified according to the Octoechos a posteriori. While early manuscripts of Greek chant always used modal signatures, the fully notated graduals and antiphonaries of the first generation, written by Frankish cantors, report many details about accentuation and ornamentation, but the melodic structure was remembered orally by tropes. Sometimes a tonary was attached to these manuscripts, and the cantors could use it by looking for the incipit of an antiphon in question to find the right psalmody according to the mode and the melodic ending of the antiphon, which was sung as a refrain during the recitation of the psalm. A Greek psaltes would sing a completely different melody according to the echos indicated by the modal signature, while Frankish cantors had to remember the melody of a certain Roman chant before they communicated their idea of its mode and its psalmody in a tonary—for all the cantors who would follow them. In this process of chant transmission, which followed Charlemagne's reform, the so-called "Gregorian chant" or Franco-Roman chant, as it was written down about 150 years after the reform, was born.
The function of the tonary within chant transmission explains why local schools of Latin chant can be studied by their tonary. Hence, the tonary was still substantial for every chant reform between the 10th and the 12th centuries, like the reform of the Cluniac Monastic Association, the reform of a monastic orders like the one around Bernard of Clairvaux for the Cistercians, a papal reform, like Abbot Desiderius realized at the Abbey Montecassino, or the reform of some monasteries of a certain region, as Abbot William of Volpiano did for certain Abbeys in Burgundy and Normandy.
The Carolingian names or "Byzantine" intonations for the 8 tones
In Carolingian times each of the eight sections was opened by an intonation formula using the names like "Nonannoeane" for the authentic and "Noeagis" or "Noeais" for the plagal tones. In the living traditions of Orthodox chant, these formulas were called "enechemata" and they were used by a protopsaltes to communicate the basis tone for the ison-singers as well as the first note of the chant for the other singers.In his theoretical tonary "Musica disciplina", Aurelian of Réôme asked a Greek about the meaning of the intonation syllables used in Latin tonaries:
The practice of using abstract syllables for the intonation, as it was common for the use of enechemata among Byzantine psaltes, was obviously not familiar to Aurelian of Réôme. It was probably imported by a Byzantine legacy, when they introduced the Greek Octoechos by a series of procession antiphons used for the feast of Epiphany. Although the Latin names were not identical, there is some resemblance between the intonation formula of the echos plagios tetartos νὲ ἅγιε and the Latin name "Noeagis", used as a general name for all four plagal tones. But there are some more obvious cases as particular names like "Aianeoeane" or "Aannes" which can be found in very few tonaries between Liège, [|Paris], Fleury, and Chartres. Two of these tonaries have treatises and use a lot of Greek terms taken from Ancient Greek theory.
