Literally “song” in Italian, the canzone is a lyric poem originating in medieval Italy and France and usually consisting of hendecasyllabic lines with end-rhyme. Early versions include Petrarch’s five to six-line stanzas plus an envoi, as well as Dante’s modification: five twelve-line stanzas with repeated end words, finished by a five-line envoi. The canzone influenced the development of the sonnet and later writers such as James Merrill, W.H. Auden, and Ezra Pound took up the form.
