A whole note (American) or semibreve (British) is a kind of note used in music notation. It has a time duration of four beats in 4
4 time.
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 Roman chant and Gallican chant.
In languages with quantitative poetic metres, such as Ancient Greek, Latin, Arabic, Sanskrit, and classical Persian, an anceps is a position in a metrical pattern which can be filled by either a long or a short syllable.
An iamb or iambus is a metrical foot used in various types of poetry. Originally the term referred to one of the feet of the quantitative meter of classical Greek prosody: a short syllable followed by a long syllable. This terminology was adopted in the description of accentual-syllabic verse in English, where it refers to a foot comprising an unstressed syllable followed by a stressed syllable.
The foot is the basic repeating rhythmic unit that forms part of a line of verse in most Indo-European traditions of poetry, including English accentual-syllabic verse and the quantitative meter of classical ancient Greek and Latin poetry. The unit is composed of syllables, and is usually two, three, or four syllables in length. The most common feet in English are the iamb, trochee, dactyl, and anapest. The foot might be compared to a bar, or a beat divided into pulse groups, in musical notation.
In music, a double whole note (American), breve (international), or double note is a note lasting two times as long as a whole note. It is the second-longest note value still in use in modern music notation.
A neume is the basic element of Western and Eastern systems of musical notation prior to the invention of five-line staff notation.
In linguistics, syllable weight is the concept that syllables pattern together according to the number and/or duration of segments in the rime. In classical Indo-European verse, as developed in Greek, Sanskrit, and Latin, distinctions of syllable weight were fundamental to the meter of the line.
In medieval music, the rhythmic modes were set patterns of long and short durations. The value of each note is not determined by the form of the written note, but rather by its position within a group of notes written as a single figure called a "ligature", and by the position of the ligature relative to other ligatures. Modal notation was developed by the composers of the Notre Dame school from 1170 to 1250, replacing the even and unmeasured rhythm of early polyphony and plainchant with patterns based on the metric feet of classical poetry, and was the first step towards the development of modern mensural notation. The rhythmic modes of Notre Dame Polyphony were the first coherent system of rhythmic notation developed in Western music since antiquity.
In music notation, a note value indicates the relative duration of a note, using the texture or shape of the notehead, the presence or absence of a stem, and the presence or absence of flags/beams/hooks/tails. Unmodified note values are fractional powers of two, for example one, one-half, one fourth, etc.
Mensural notation is the musical notation system used for European vocal polyphonic music from the later part of the 13th century until about 1600. The term "mensural" refers to the ability of this system to describe precisely measured rhythmic durations in terms of numerical proportions between note values. Its modern name is inspired by the terminology of medieval theorists, who used terms like musica mensurata or cantus mensurabilis to refer to the rhythmically defined polyphonic music of their age, as opposed to musica plana or musica choralis, i.e., Gregorian plainchant. Mensural notation was employed principally for compositions in the tradition of vocal polyphony, whereas plainchant retained its own, older system of neume notation throughout the period. Besides these, some purely instrumental music could be written in various forms of instrument-specific tablature notation.
A catalectic line is a metrically incomplete line of verse, lacking a syllable at the end or ending with an incomplete foot. One form of catalexis is headlessness, where the unstressed syllable is dropped from the beginning of the line.
Stichometry refers to the practice of counting lines in texts: Ancient Greeks and Romans measured the length of their books in lines, just as modern books are measured in pages. This practice was rediscovered by German and French scholars in the 19th century. Stichos is the Greek word for a 'line' of prose or poetry and the suffix '-metry' is derived from the Greek word for measurement.
The Iambic trimeter is a meter of poetry consisting of three iambic units per line.
Ars longa, vita brevis is a Latin translation of an aphorism coming originally from Greek.
A longa, long, quadruple note (Am.), or quadruple whole note is a musical note that could be either twice or three times as long as a breve, four or six times as long as a semibreve, that appears in early music. The number of breves in a long was determined by the "modus" or "mode" of a passage. Sections in perfect mode used three breves to the long while sections in imperfect mode used two breves to the long. Imperfect longs, worth two breves, existed in perfect mode from the earliest sources, while the fourteenth century saw the introduction of perfect longs, worth three breves, in imperfect mode through the use of dots of addition.
In Ancient Greek and Latin metre, brevis in longo is a short syllable at the end of a line that is counted as long. The term is short for (syllaba) brevis in (elemento) longo, meaning "a short [syllable] in place of a long [element]." Although the phenomenon itself has been known since ancient times, the phrase is said to have been invented by the classical scholar Paul Maas.
In medieval music theory, the Latin term modus can be used in a variety of distinct senses. The most commonly used meaning today relates to the organisation of pitch in scales. Other meanings refer to the notation of rhythms.
Latin prosody is the study of Latin poetry and its laws of meter. The following article provides an overview of those laws as practised by Latin poets in the late Roman Republic and early Roman Empire, with verses by Catullus, Horace, Virgil and Ovid as models. Except for the early Saturnian poetry, which may have been accentual, Latin poets borrowed all their verse forms from the Greeks, despite significant differences between the two languages.
A maxima, duplex longa, larga, or octuple whole note was a musical note used commonly in thirteenth and fourteenth century music and occasionally until the end of the sixteenth century. It was usually twice or, rarely, three times as long as a longa, four or six or nine times as long as a breve, and 8, 12, 18, or 27 times as long as a semibreve. Like the stem of the longa, the stem of the maxima generally pointed downwards except occasionally when it appeared on the bottom line or space. Before around 1430, the maxima was written with a solid, black body. Over the course of the fifteenth century, like most other note values, the head of the maxima became void.
