Guido of Arezzo was an Italian music theorist and pedagogue of High medieval music. A Benedictine monk, he is regarded as the inventor—or by some, developer—of the modern staff notation that had a massive influence on the development of Western musical notation and practice. Perhaps the most significant European writer on music between Boethius and Johannes Tinctoris, after the former's De institutione musica, Guido's Micrologus was the most widely distributed medieval treatise on music.
Guillaume de Machaut was a French composer and poet who was the central figure of the ars nova style in late medieval music. His dominance of the genre is such that modern musicologists use his death to separate the ars nova from the subsequent ars subtilior movement. Regarded as the most significant French composer and poet of the 14th century, he is often seen as the century's leading European composer.
Ars antiqua, also called ars veterum or ars vetus, is a term used by modern scholars to refer to the Medieval music of Europe during the High Middle Ages, between approximately 1170 and 1310. This covers the period of the Notre-Dame school of polyphony, and the subsequent years which saw the early development of the motet, a highly varied choral musical composition. Usually the term ars antiqua is restricted to sacred (church) or polyphonic music, excluding the secular (non-religious) monophonic songs of the troubadours, and trouvères. Although colloquially the term ars antiqua is used more loosely to mean all European music of the 13th century, and from slightly before.
Ars nova refers to a musical style which flourished in the Kingdom of France and its surroundings during the Late Middle Ages. More particularly, it refers to the period between the preparation of the Roman de Fauvel (1310s) and the death of composer Guillaume de Machaut in 1377. The term is sometimes used more generally to refer to all European polyphonic music of the fourteenth century. For instance, the term "Italian ars nova" is sometimes used to denote the music of Francesco Landini and his compatriots, although Trecento music is the more common term for the contemporary 14th-century music in Italy. The "ars" in "ars nova" can be read as "technique", or "style". The term was first used in two musical treatises, titled Ars novae musicae by Johannes de Muris, and a collection of writings attributed to Philippe de Vitry often simply called "Ars nova" today. Musicologist Johannes Wolf first applied to the term as description of an entire era in 1904.
Ars subtilior is a musical style characterized by rhythmic and notational complexity, centered on Paris, Avignon in southern France, and also in northern Spain at the end of the fourteenth century. The style also is found in the French Cypriot repertory. Often the term is used in contrast with ars nova, which applies to the musical style of the preceding period from about 1310 to about 1370; though some scholars prefer to consider ars subtilior a subcategory of the earlier style. Primary sources for ars subtilior are the Chantilly Codex, the Modena Codex, and the Turin Manuscript.
Anonymous IV is the designation given to the writer of an important treatise of medieval music theory. He was probably an English student working at Notre Dame de Paris, most likely in the 1270s or 1280s. Nothing is known about his life. His writings survive in two partial copies from Bury St Edmunds; one from the 13th century, and one from the 14th.
Musica ficta was a term used in European music theory from the late 12th century to about 1600 to describe pitches, whether notated or added at the time of performance, that lie outside the system of musica recta or musica vera as defined by the hexachord system of Guido of Arezzo.
Franco of Cologne was a German music theorist and possibly a composer. He was one of the most influential theorists of the Late Middle Ages, and was the first to propose an idea which was to transform musical notation permanently: that the duration of any note should be determined by its appearance on the page, and not from context alone. The result was Franconian notation, described most famously in his Ars cantus mensurabilis.
Baude Cordier was a French composer in the ars subtilior style of late medieval music. Virtually nothing is known of Cordier's life, aside from an inscription on one of his works which indicates he was born in Rheims and had a Master of Arts. Some scholars identify him with Baude Fresnel, a harpist and organist in the court of Philip the Bold, though other scholars have rejected this.
The Corpus mensurabilis musicae (CMM) is a collected print edition of most of the sacred and secular vocal music of the late medieval and Renaissance period in western music history, with an emphasis on the central Franco-Flemish and Italian repertories. CMM is a publication of the American Institute of Musicology, and consists of 109 series as of 2007. Renowned composers whose works have appeared in other collected editions, such as Josquin des Prez, Giovanni Pierluigi da Palestrina, and Orlande de Lassus, are generally excluded from the set.
Richard Loqueville was a French composer active during the transition between Medieval and Renaissance music. A musician at Cambrai Cathedral, Loqueville was a harpist and teacher, whose students included Edward III, Duke of Bar and the influential composer Guillaume Du Fay.
Claude Victor Palisca was an American musicologist. An internationally recognized authority on early music, especially opera of the Renaissance and Baroque periods, he was the Henry L. and Lucy G. Moses Professor Emeritus of Music at Yale University. Palisca is best known for co-writing the standard textbook A History of Western Music, as well as for his substantial body of work on the history of music theory in the Renaissance, reflected in his editorship of the Yale Music Theory in Translation series and in the book Humanism in Italian Renaissance Musical Thought (1985). In particular, he was the leading expert on the Florentine Camerata. His 1968 book Baroque Music in the Prentice-Hall history of music series ran to three editions.
Don Harran was professor of musicology at the Hebrew University of Jerusalem.
Anthony D'Accone was an American musicologist. He was the author of documentary studies of the musicians and institutions that produced the music of the Florentine and Siennese Renaissance. His many modern editions of the music of this culture made available to present-day performers and scholars for the first time in several centuries a wide-ranging picture of the musical life in Tuscany during the Renaissance. Musicologist Lewis Lockwood stated that his body of work "substantially extends current knowledge of the music history of the Italian Renaissance."
Jehan Vaillant was a French composer and music theorist. He is named immediately after Guillaume de Machaut by the Règles de la seconde rhétorique, which describes him as a "master … who had a school of music in Paris". Besides five pieces of music surviving to his name, he was also the author of a treatise on tuning. With Grimace and F. Andrieu and P. des Molins, Vaillant was part of the post-Machaut generation whose music shows few distinctly ars subtilior features, leading scholars to recognize Vaillant's work as closer to the ars nova style of Machaut.
P. des Molins, probably Pierre des Molins, was a French composer-poet in the ars nova style of late medieval music. His two surviving compositions – the ballade De ce que fol pensé and rondeau Amis, tout dous vis – were tremendously popular as they are among the most transmitted pieces of fourteenth-century music. The ballade is found in 12 medieval manuscript sources and featured in a c. 1420 tapestry; the rondeau is found in 8 sources and referenced by the Italian poet Simone de' Prodenzani. Along with Grimace, Jehan Vaillant and F. Andrieu, Molins was one of the post-Guillaume de Machaut generation whose music shows few distinctly ars subtilior features, leading scholars to recognize Molins's work as closer to the ars nova style of Machaut.
David Fallows is an English musicologist specializing in music of the late Middle Ages and early Renaissance, as well as the performance practice of music. He is a leader in fifteenth-century music studies, particularly secular song, Guillaume Dufay, and Josquin des Prez, both the subject of landmark biographies Fallows has written.
Gilet Velut was a French composer of the early Renaissance.
Magister Franciscus was a French composer-poet in the ars nova style of late medieval music. He is known for two surviving works, the three-part ballades: De Narcissus and Phiton, Phiton, beste tres venimeuse; the former was widely distributed in his lifetime. Modern scholarship disagrees on whether Franciscus was the same person as the composer F. Andrieu.
Gilbert Reaney was an English musicologist who specialized in medieval and Renaissance music, theory and literature. Described as "one of the most prolific and influential musicologists of the past century", Reaney made significant contributions to his fields of expertise, particularly on the life and works of Guillaume de Machaut, as well as medieval music theory.
