Yes, Leonin is the first known significant composer of polyphonic organum, which was two or more melodic voices used in Medieval chants.
There are several medieval composers who can make a valid claim to being the 'most important'.Why don't you start with Guillaume de Machaut - a very serious contender?When you know a little about Guillaume, research Perotin and Leonin - and decide if you think they were more, or less, important.the catholic church
yes he is the earliest known polyphony composer
The rhythm of early notated music came from a few different sources. One idea is that it was first notated with the Greeks.
They were both famous composers of the time. They are also two of the few composers from the Middle Ages who are known to have existed then. --- They developed organum, which was a step between unison chanting and counterpoint.
there were no significant composers in the middle ages era. Music, and culture in general, saw a comeback during the Renaissance, but the Middle, or Dark, Ages were times of feudalism and very limited communication.
Leonin, who worked in Paris during the second half of the 12th century, and Perotin, who continued after Leonin, developed polyphonic organum. This was a type of music composition the was developed into counterpoint. Prior to organum, music was very simple, with a single melodic line, sung in unison. There were possible additions, such as a drone, which stuck to a single tone. Organum used the same melodic line duplicated in easy ways such as at an interval of a third or fourth above the main line. This was developed with increasing complexity until, with counterpoint, second and third melodic lines that were very different melodies were used simultaneously, related to each other in accordance with a set of rules developed for the purpose.
Leonin died in 1201.
