Conductus

In medieval music, conductus is a type of liturgical vocal composition for one or more voices. The word derives from Latin conducere (to escort), and the conductus was most likely sung while the lectionary was carried from its place of safekeeping to the place from which it was to be read. The conductus was one of the principal types of vocal composition of the ars antiqua period of medieval music history.

The form most likely originated in the south of France around 1150, and reached its peak development during the activity of the Notre Dame School in the early 13th century. Most of the conductus compositions of the large mid-13th century manuscript collection from Notre Dame are for two or three voices. Conductus are also unique in the Notre Dame repertory in admitting secular melodies as source material, though sacred melodies were also commonly used. Common subjects for the songs were lives of the saints, feasts of the Lord, the Nativity, as well as more current subjects such as exemplary behavior of contemporary witnesses to the faith, such as Thomas ? Becket. A significant and interesting repertory of conductus from late in the period consists of songs which criticize abuses by the clergy, including some which are quite outraged. While it might be difficult to imagine them being sung in church, it is possible that the repertory may have had an existence beyond its documented liturgical use.

Almost all composers of conductus are anonymous. Some of the poems, all of which are in Latin, are attributed to poets such as Philip the Chancellor and John of Howden.

The style of the conductus was usually rhythmic, as befitting music accompanying a procession, and almost always note-against-note. Stylistically it was utterly different from the other principal liturgical polyphonic form of the time, organum, in which the voices usually moved at different speeds; in conductus, the voices sang together, in a style also known as discant.

Music theorists who wrote about the conductus include Franco of Cologne, who advocated having a beautiful melody in the tenor, Johannes de Garlandia, and Anonymous IV. Early 14th century theorist Jacques of Li?ge, a vigorous defender of the ars antiqua style against the new "immoral and lascivious" ars nova style, lamented the disinterest of contemporary composers in the conductus. The conductus lasted longest in Germany, where it was documented into the 14th century.
