TrecentoThe Trecento (treɪˈtʃɛntoʊ, also UStrɛˈ-, ˌtreˈtʃɛnto; short for milletrecento, "1300") refers to the 14th century in Italian cultural history. The Trecento is considered to be the beginning of the Italian Renaissance or at least the Proto-Renaissance in art history. Painters of the Trecento included Giotto di Bondone, as well as painters of the Sienese School, which became the most important in Italy during the century, including Duccio di Buoninsegna, Simone Martini, Lippo Memmi, Ambrogio Lorenzetti and his brother Pietro.
HeterophonyIn music, heterophony is a type of texture characterized by the simultaneous variation of a single melodic line. Such a texture can be regarded as a kind of complex monophony in which there is only one basic melody, but realized at the same time in multiple voices, each of which plays the melody differently, either in a different rhythm or tempo, or with various embellishments and elaborations. The term was initially introduced into systematic musicology to denote a subcategory of polyphonic music, though is now regarded as a textural category in its own right.
Secular musicNon-religious secular music and sacred music were the two main genres of Western music during the Middle Ages and Renaissance era. The oldest written examples of secular music are songs with Latin lyrics. However, many secular songs were sung in the vernacular language, unlike the sacred songs that followed the Latin language of the Church. These earliest types were known as the chanson de geste (song of deeds) and were popular amongst the traveling jongleurs and minstrels of the time.
Formes fixesThe formes fixes (fɔʁm fiks; singular: forme fixe, "fixed form") are the three 14th- and 15th-century French poetic forms: the ballade, rondeau, and virelai. Each was also a musical form, generally a chanson, and all consisted of a complex pattern of repetition of verses and a refrain with musical content in two main sections. All three forms can be found in 13th-century sources, but a 15th-century source gives Philippe de Vitry as their first composer while the first comprehensive repertory of these forms was written by Guillaume de Machaut.
PlainsongPlainsong or plainchant (calque from the French plain-chant; cantus planus) is a body of chants used in the liturgies of the Western Church. When referring to the term plainsong, it is those sacred pieces that are composed in Latin text. Plainsong was the exclusive form of Christian church music until the ninth century, and the introduction of polyphony. The monophonic chants of plainsong have a non-metric rhythm. Their rhythms are generally freer than the metered rhythm of later Western music, and they are sung without musical accompaniment.
