Chant Glossary

Patrick Williams · March 12, 2023

a (auge, augete) – significative letter used in some MSS to indicate long notes, but in others to indicate higher (altius) notes

accent – a means of emphasizing one or more notes by volume (dynamic accent), pitch (tonic accent), or duration (agogic accent); except in words of only one or two syllables, the liturgical books mark the stressed syllable with an acute accent (´), which sometimes differs from the actual accentuation of medieval Latin; in chant, Hebrew words are typically stressed on the final syllable, regardless of where the accent is marked in the text

accentualism (rhetorical or oratorical approach) – interpretive approach emphasizing speech rhythm

adiastematic neumes – neumes written without a staff “in open field” (in campo aperto)

agogic accent – the emphasis of one or more notes by means of duration; classical Latin had long and short vowel quantities, which were no longer observed in the Early Middle Ages

Aribo – eleventh-century Benedictine monk and music theorist

bar lines – editorial markings used in the Vatican edition and other editions to indicate phrasing, breathing, and rests

Biezen, Dr. Jan van (1927–2021) – proponent of mensuralism/proportionalism, author of Rhythm, Meter and Tempo in Gregorian Chant

c (celeritas or celeriter) – significative letter used in many MSS to indicate short notes

C – the St. Gall Cantatorium, Codex Sangallensis 359, from between 922 and 926; includes only graduals, alleluias, and tracts

cantilena metensis (Messine chant) – a name for what would later be known as Gregorian chant

cantus planus – see plainsong

Cardine, Dom Eugène, O.S.B. (1905–88) – author of Gregorian Semiology, founder of the “new Solesmes” style

Ch – Chartres 47, a gradual from the tenth century, destroyed in 1944

climacus (pl. climaci) – a descending neumatic element, usually three notes, high-low-lower

clivis (also clinis, flex, or flexa; pl. clives) – a neumatic sign composed of a two notes, high-low

crasis – the fusion of two or more identical vowels, e.g. suum, tuum, Kyrie eleison, filii Israel

cursive – a connected style of writing all or part of a neume, signifying short note values; just as in ordinary penmanship, the objective of cursive writing is not to be ornate or elegant, but to be faster and therefore more efficient

diastematic neumes – “heightened” neumes written either on a staff or otherwise indicating pitch according to their position on the page

disaggregate neume – also called a praepunctis neume; a neume with an initial punctum (usually a tractulus or uncinus in the MSS) separated from the rest of the neume with a neumatic break; the first note is considered long not only in proportional rhythm and semiology, but also in more mature or advanced presentations of the Solesmes method

dot – see punctum mora

dynamic accent – the emphasis of one or more notes by means of volume; by the time of the earliest extant chant MSS, Latin word stress is generally considered to have been dynamic rather than tonic or quantitative

E – the Einsiedeln Gradual (E), Codex Einsidlensis 121, from between approximately 960 and 996

episema (pl. episemata) – 1. in the St. Gall neumes, a stroke added to the top or end of a neumatic element to signify lengthening; 2. in the Solesmes and some other editions, a horizonal line, resembling a tenuto mark in modern music, indicating a relatively long note; 3. in the Solesmes editions, a vertical line indicating the placement of the ictus but also used to differentiate the salicus from the scandicus , in which case the marked note is held

equalism – style of chant assigning equal durational values to all notes except at cadences (phrase endings) or the mora vocis

Euouae – abbreviation for the vowels of saeculorum amen, used to indicate which termination or conclusion of the Gloria Patri is to be used

franculus – see gutturalis

Gajard, Dom Joseph, O.S.B. (1885–1972) – longtime choirmaster of Solesmes, successor to Dom Mocquereau

isolated – used to describe the setting of a syllable to a single note; a one-note neume used by itself; cf. syllabic, in composition

isometric – variants of Reformation-era chorales and psalm tunes with mostly equal note values; cf. rhythmic

Kainzbauer, Xaver – musicologist known for semiology, melodic restoration, digitalization of manuscript images, Antiphonale Synopticum, Graduale Authenticum, and Graduale Synopticum

L – the Laon Gradual, Codex Laudunensis 239, from around the year 930; the Laon municipal library website actually dates it to the ninth century

liquescent – a note used in conjunction with one or more consonants or a diphthong, which occurs only at the end of a neume or in isolation, never in the middle of a neume; in the Vatican edition and most other editions, notated as a smaller note (or more than one note, in the case of the ancus/climacus) when it represents a higher or lower pitch; in most adiastematic MSS, liquescent notes have a rounded appearance in comparison to their non-liquescent counterparts

m (mediocritas) – significative letter meaning moderately

Medicaean edition – any of the various altered editions of chant that were published beginning in the Renaissance era until they were superseded by the Vatican edition

melisma (pl. melismata; adj. melismatic) – a neume composed of multiple elements; a single syllable sung to many notes; cf. oligotonic, syllabic

neumatic break or cut – a separation of one neumatic element from another; a break in the neume, generally considered “expressive” and lengthening the preceding note unless at a melodic low point; cf. disaggregate neume

neume (or neum; adj. neumatic) – properly, all notes sung to a single syllable; commonly, a neumatic sign, element, figure, component, group, graphic, or glyph (all of these terms are used interchangeably)

Nickel, Royce – editor of the Graduale Renovatum

non-cursive – a style of writing all or part of a neume with separation between the notes, with the addition of an episema, or in an angular fashion, signifying long note values

normal syllabic value (Lat. valor syllabicus medius, It. tempo sillabico normale, Fr. temps syllabique moyen) – the normal duration of a syllable set to a single note; in proportional rhythm, the normal syllabic value is relatively long, of one beat; short neumes of half a beat are the exception, not the rule; in semiology, the normal syllabic value is also relatively long, but may be augmented or diminished on account of the text, independent of the neumes themselves; in the Solesmes method, the normal syllabic value is short and indivisible, with long or doubled isolated syllables being the exception

nuance – according to the theory of Mocquereau, the “long” neumatic signs indicate interpretive nuances, not quantitative proportions; cf. proportional rhythm

officium – another name for the introit, used in the Dominican and some other rites

oral tradition – the transmission of music “by mouth” and “by ear” (aural) without notation

Ordinary – the chants that are repeated at Masses throughout the year: Kyrie, Gloria, Credo, Sanctus, Agnus Dei, Ite missa est; note that the Gregorian Credo chants are numbered separately from the rest of the Ordinary; in polyphony, the Benedictus is a separate movement, and the Ite missa est-Deo gratias is generally not included; many prayers said by the priest are non-choral parts of the Ordinary

organum, parallel (pronounced with the stress on the first syllable, órganum) – a medieval style of singing in parallel intervals of perfect fourths and fifths

oriscus (pl. orisci) – in the MSS, a neumatic sign with a wavy (not jagged or serrated!) appearance, which is never followed by a unison note

ornamental note – a note sung lightly and shorter than the normal short value; in some interpretations, may include the quilisma, an auxiliary note in conjuction with the oriscus, initio debiles (weak beginning) notes, and passing tones within otherwise long neumatic elements

pes (pl. pedes) or podatus (pl. podati) – a neumatic sign composed of a two notes, low-high

plainsong (or plainchant; Lat. cantus planus) – a name used to differentiate chant (sometimes called cantus firmus in Church documents) from harmonized (“figured”) music

porrectus (pl. porrecti) – a neumatic sign composed of a three notes, high-low-high

porrectus subbipunctis – a neumatic sign composed of a five notes, high-low-high-low-lower; in the Vatican edition, notated as a porrectus followed by two puncta inclinata

praepunctis – see disaggregate neume

pressus major – a neumatic sign comprised of two unison notes followed by a lower note, the second note being an oriscus; in the Vatican edition, printed as punctum+clivis

proportional rhythm – the interpretation of the long and short neumatic signs in 2:1 proportion; cf. nuance

psalm tone – a melodic formula for chanting psalm verses or similar liturgical texts

punctum (pl. puncta) – literally, a point; a neumatic sign indicating a short note; the former practice of referring to the tractulus also as a punctum is now nonstandard

punctum inclinatum – a diamond- or rhombus-shaped punctum; in the Vatican edition, used only for two or more descending notes

punctum mora (pl. puncta morae) – an augmentation dot; in the Solesmes edition, an editorial addition (supposedly), which doubles the preceding note

quilisma (or tremula) – a neumatic sign with a jagged or serrated appearance, probably indicating a rising portamento or slide between notes; there is also a descending version in Mp and other notations

recitative – term used in classical music for a style of singing a text more or less in speech rhythm, with the notation indicating relatively long and short notes, not exact rhythmic proportions; liturgically, the chants for the the prayers of the celebrant, the readings, and the psalmody of the Divine Office are recited on pitch according to a formula; the most basic form of liturgical recitative is recto tono

recto tono – the recitation of text on a single pitch (monotone); cf. recitative

responsorium – as far as the chants of the Mass are concerned, another name for the gradual, used in the Dominican and some other rites

rhythmic – in reference to Reformation-era chorales and psalm tunes, the version of the melody retaining the original rhythm; cf. isometric

semiology – the “new Solesmes” style inaugurated by Dom Cardine, based on a nuanced, non-proportional interpretation of the oldest extant sources

significative letter – a letter or combination of letters used in some MSS to signify melody, rhythm, volume, tone, etc.; also called Romanian letters after the deacon Romanus, who established the choir school (schola cantorum) at St. Gall in the early ninth century; cf. a, c, m, t

Solesmes – Benedictine monastery reestablished by Dom Prosper Guéranger after the French Revolution; pivotal in the 19th- and 20th-century restoration of chant; as an adjective, Dom Mocquereau’s style of interpretation (which is now known to be based upon a misinterpretation of some of the oldest MS evidence) as revised and codified in the Solesmes chant books, including the Liber Usualis, and further developed under Dom Gajard

Random Quote

It was thought important that the song should actually accompany the distribution of Communion. A Carolingian explanation of the Mass remarks that during the Communion “soft melody should touch the ear [of the faithful] so that hearing this sound they would busy themselves less with distracting thoughts and … their hearts would be moved to humble love for that which they receive.”

— Father Josef Andreas Jungmann
