Ars Antiqua Continued

The Ars Antiqua (“Old Art,” late 12th through 13th Centuries) is characterized by development of polyphonic forms.  Various kinds of organum appeared first, followed by Polyphonic Conductus and Motets.  Also at this time:

·         Rhythmic modes were codified

·         Notation was invented that could express rhythm as well as pitch

·         Meter was always in triple subdivisions

·         Gregorian chant still used prominently

·         Ranges of vocal music still limited

·         Melodies are linear

·         Harmonies are simple, chromaticism is avoided

Prominent Forms of the Ars Antiqua

·         Conductus: polyphonic conductus has characteristics in common with monophonic conductus, which used newly composed (not Gregorian) melodies and which were non-liturgical but religiously oriented.  Polyphonic conductus resembles the discant sections of Notre Dame Organum with rhythmic tenor and 2-3 upper parts. 

·         Motet: Becomes popular in 2nd half of 13th Century.

·         The motet also originates from clausula, which became a more independent item, eventually separated from the melismatic organum (“organum purum”) sections.  They were musical alternatives that could be used interchangeably.

·         The main difference between motets and other polyphonic forms is that texts are added to upper voices

·         At first texts were in Latin

·         Later French texts were added to upper voices; sometimes different texts in each voice; sometimes even different languages in each voice

·         The Duplum starts to be called motetus

·         Naming conventions for motets: use first word or two of each line (incipits) starting from top voice

·         Gregorian melody (or any pre-existing melody used as basis for another composition) is called a cantus firmus.

Further Developments in Motets

·         Franconian Motet (described by Franco of Cologne, composer 1250-80): earliest motets had the upper voices in approximately the same rhythm; now the top voice is fastest moving and has the most text; the motetus has a bit less text and slightly simpler rhythm; tenor still longest note values.  Franco wrote treatise Art of Mensurable Music [c.1280])that  discussed rhythmic practices of the 13th Century.  Mensurable means that durations are fixed

·         Petronian Motet (defined by Petrus de Cruce, composer 1270-1300).  Very similar to Franconian, but triplum is freer in rhythm (even faster than Franconian), tenor usually has very uniform rhythm

·         By late 13th century, there were motets that were entirely secular; even tenor was newly composed or borrowed from a secular song

·         Hocket (a technique or a type of composition - name is French for hiccough): distributes melodic line between different voices so that one sounds while the other is silent
