Adam de la Halle, (1240–1287) also known as Adam le Bossu (1240–1287), was a French trouvère, poet and musician. Adam's literary and musical works include chansons and jeux-partis in the style of the trouvères; polyphonic rondel and motets in the style of early liturgical polyphony; and a musical play, Jeu de Robin et Marion, which is considered the earliest surviving secular French play with music. He was a member of the Confrérie des jongleurs et bourgeois d'Arras.

Guilhem Ademar was a troubadour from the Gévaudan in France. He travelled between the courts of Albi, Toulouse, Narbonne, and Spain. He achieved fame enough during his life to be satirised by the nobleman and monk, Monge de Montaudon. Guilhem entered holy orders towards the end of his life. Sixteen poems—fourteen cansos, a sirventes, and a partimen with Eble d'Ussel—form his surviving corpus. His cansos are his most famous pieces. Usually humorous, several mock the poetry of Ademar's more illustrious contemporary Arnaut Daniel. One canso survives with a tune.

Albertet de Sestaro, sometimes called Albertet de Terascon, was a Provençal jongleur and troubadour from the Gapençais. Of his total oeuvre, twenty three poems survive. "Albertet" or "Albertetz" is the Occitan diminutive of Albert. Unqualified it usually refers to Albertet de Sestaro, but there was an Albertet Cailla.

Alfonso X was the king of Castile, León and Galicia from 30 May 1252 until his death in 1284. During the election of 1257, a dissident faction chose him to be king of Germany on 1 April. He renounced his claim to Germany in 1275, and in creating an alliance with the Kingdom of England in 1254, his claim on the Duchy of Gascony as well.

F. Andrieu was a French composer in the ars nova style of late medieval music. Nothing is known about him except that he wrote a double ballade déploration, Armes, amours/O flour des flours, on the death of Guillaume de Machaut in 1377. The work has been widely praised and analyzed; it is notable for being one of two extant four-part double ballades of medieval music, the only know contemporary musical setting of Eustache Deschamps and the earliest representative of the longstanding medieval and Renaissance lamentation tradition for a fellow composer. He may be the same person as Magister Franciscus, although the scholarly consensus on this identification is unclear. With P. des Molins, Jehan Vaillant and Grimace, Andrieu was one of the "post-Machaut" generation whose pieces retain enough ars nova qualities to be separable from composers of ars subtilior.

Berenguier de Palazol, Palol, or Palou was a Catalan troubadour from Palol in the County of Roussillon. Of his total output twelve cansos survive, and a relatively high proportion—eight—with melodies.

Bernart de Ventadorn was a prominent troubadour of the classical age of troubadour poetry. Now thought of as "the Master Singer" he developed the cançons into a more formalized style which allowed for sudden turns. He is remembered for his mastery as well as popularisation of the trobar leu style, and for his prolific cançons, which helped define the genre and establish the "classical" form of courtly love poetry, to be imitated and reproduced throughout the remaining century and a half of troubadour activity.

Born in Sarlat in the Périgord, he first travelled with the Fourth Crusade and settled down in the Kingdom of Thessalonica at the court of Boniface of Montferrat (1204–1208/10) before moving back to western Europe, where he sojourned at the court of Alfonso IX of León (1210–11) and in Lombardy (1219–1222/24). He wrote fourteen surviving lyrics: ten cansos, one tenso, one descort, one sirventes, and one Crusade song. He was partial to refrain rhyming and coblas capfinidas.

He was one of the most influential theorists of the late Medieval era, 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.

Giraut de Bornelh, whose first name is also spelled Guiraut and whose toponym as de Borneil or de Borneyll, was a troubadour connected to the castle of the viscount of Limoges. He is credited with the formalisation, if not the invention, of the "light" style, or trobar leu.

Godric of Finchale was an English hermit, merchant and popular medieval saint, although he was never formally canonised. He was born in Walpole in Norfolk and died in Finchale in County Durham.

Grimace was a French poet and composer of the ars nova style in late medieval music. Virtually nothing is known about Grimace's life other than speculative information based on the circumstances and content of his five surviving compositions of formes fixes; three ballades, a virelai and rondeau. Three of his works were included in the Chantilly Codex, which is an important source of ars subtilior music. However, along with P. des Molins, Jehan Vaillant and F. Andrieu, Grimace was one of the post-Guillaume de Machaut generation whose music shows few distinctly ars subtilior features, leading scholars to recognize Grimace's work as closer to the ars nova style of Machaut. His most often performed work is the virelai and proto-battaglia: A l’arme A l’arme.

Immensely influential, Machaut is regarded as the most important composer and poet of the 14th century and is the first significant composer whose name is known. Daniel Leech-Wilkinson called him "the last great poet who was also a composer", and well into the 15th century Machaut's poetry was greatly admired and imitated by other poets, including Geoffrey Chaucer.

Martin Codax or Martim Codax was a Galician medieval joglar - possibly from Vigo, Galicia in present-day Spain. He may have been active during the middle of the thirteenth century, judging from scriptological analysis. He is one of only two out of a total of 88 authors of cantigas d'amigo who used only the archaic strophic form aaB. He employed an archaic rhyme-system whereby i~o / a~o were used in alternating strophes. In addition Martin Codax consistently utilised a strict parallelistic technique known as leixa-pren. There is no documentary biographical information concerning the poet, dating the work at present remains based on theoretical analysis of the text.

Perotinus Magnus, was a composer from around the late 12th century, associated with the Notre Dame school of polyphony in Paris and the ars antiqua musical style. The title Magister Perotinus means that he was licensed to teach. The only information on his life with any degree of certainty comes from an anonymous English student at Notre Dame known as Anonymous IV. It is assumed that he was French and named Pérotin, a diminutive of Peter, but attempts to match him with persons in other documents remain speculative.
