A madrigal is a secular vocal music composition, usually a partsong, of the Renaissance and early Baroque eras. Traditionally, polyphonic madrigals are unaccompanied; the number of voices varies from two to eight, and most frequently from three to six.

Madrigals originated in Italy during the 1520s. Unlike many strophic forms of the time, most madrigals were through-composed. In the madrigal, the composer attempted to express the emotion contained in each line, and sometimes individual words, of a celebrated poem.

The madrigal originated in part from the frottola, in part from the resurgence in interest in vernacular Italian poetry, and also from the influence of the French chanson and polyphonic style of the motet as written by the Franco-Flemish composers who had naturalized in Italy during the period. A frottola generally would consist of music set to stanzas of text, while madrigals were through-composed. However, some of the same poems were used for both frottola and madrigals. The poetry of Petrarch in particular shows up in a wide variety of genres. The madrigal is related mostly by name alone to the Italian trecento madrigal of the late 13th and 14th centuries.

Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").

The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. There is also a strong connection between music and mathematics.

To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." Musicologist Jean-Jacques Nattiez summarizes the relativist, post-modern viewpoint: "The border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus ... By all accounts there is no single and intercultural universal concept defining what music might be."

Giovanni Pierluigi da Palestrina (3 February 1525 or 2 February 1526 – 2 February 1594) was an Italian Renaissance composer of sacred music and the best-known 16th-century representative of the Roman School of musical composition. He had a lasting influence on the development of church music, and his work has often been seen as the culmination of Renaissance polyphony.

Palestrina was born in the town of Palestrina, near Rome, then part of the Papal States. Documents suggest that he first visited Rome in 1537, when he is listed as a chorister at the Santa Maria Maggiore basilica. He studied with Robin Mallapert and Firmin Lebel. He spent most of his career in the city.

Palestrina came of age as a musician under the influence of the northern European style of polyphony, which owed its dominance in Italy primarily to two influential Franco-Flemish composers, Guillaume Dufay and Josquin des Prez, who had spent significant portions of their careers there. Italy itself had yet to produce anyone of comparable fame or skill in polyphony.
