The troubadour Raimbaut de Vaqueiras composed a famous contrafactum using
the melody of
a well-known estampie, fitting new words to an existing tune and thereby giving his poem immediate musical
recognition with audiences
already familiar with the melody; Guillaume de Machaut's compositional practice routinely involved adapting existing melodies for new poetic texts, demonstrating that the boundary between
composition and borrowing in medieval music was far more permeable than modern copyright thinking would suggest; Liturgical contrafacta were common throughout the Middle Ages, with secular melodies being appropriated for religious texts, as when the melody of a popular love song was given new words praising
the Virgin Mary; A student can experience contrafactum by writing new words to a familiar song melody, fitting syllables to the existing rhythmic and melodic
pattern, immediately grasping why medieval poets found this technique both convenient and musically effective; The noël, the French
Christmas song, frequently employed contrafactum, putting pious texts about the Nativity to the tunes of popular secular
songs, making sacred content accessible through familiar musical vehicles; Contrafactum reveals that in medieval culture the concepts of authorship and originality applied more to poetic texts than to melodies, which circulated as common cultural
property available for creative reuse.
