A madrigal is a form of secular vocal music most typical of the Renaissance (15th–16th centuries) and early Baroque (1580–1650) periods, although revisited by some later European composers. The polyphonic madrigal is unaccompanied, and the number of voices varies from two to eight, but the form usually features three to six voices, whilst the metre of the madrigal varies between two or three tercets, followed by one or two couplets. Unlike verse-repeating strophic forms sung to the same music, most madrigals are through-composed, featuring different music for each stanza of lyrics, whereby the composer expresses the emotions contained in each line and in single words of the poem being sung.
Madrigals written by Italianized Franco–Flemish composers in the 1520s partly originated from the three-to-four voice frottola (1470–1530); partly from composers' renewed interest in poetry written in vernacular Italian; partly from the stylistic influence of the French chanson; and from the polyphony of the motet (13th–16th centuries). The technical contrast between the musical forms is in the frottola consisting of music set to stanzas of text, whilst the madrigal is through-composed, a work with different music for different stanzas. As a composition, the madrigal of the Renaissance is unlike the two-to-three voice Italian Trecento madrigal (1300–1370) of the 14th century, having in common only the name madrigal, which some have suggested derives from the Latin matricalis (maternal) denoting musical work in service to the mother church or from the post-classical Latin matricalis (maternal, simple, primitive). Other sources note that the word "madrigal" comes from the Hebrew word "madriga" meaning "step" (the "-al" suffix of the word also is Hebrew, in this case meaning "in the style of") and describes the step-like progression of the tune. The early Christians having been Jews are believed to have brought the musical style into the Christian/Byzantine liturgy and, from there, into Gregorian chant and from there it made its way into secular song.
