Medieval Music. The Medieval period represents almost a thousand years of the music history of Europe. Much of the music of this time has been lost. This period is also called the Middle Ages and the Dark Ages. Most of the composers of this time are anonymous. That means we don´t know who they are . Plainchant. The earliest music of the Middle Ages was sung slowly and without rhythm or harmony. Everyone sang the same thing, which is singing in unison. These simple tunes were called plainchant because they were so plain and simple. These tunes are also called Gregorian Chant, which were named after Pope Gregory I. Harmony. Later on other musical lines were added, creating harmony. This is also called polyphonic music. This is music for more than one voice and it appeared during the later Medieval period. This marked the beginning of harmony. Sacred and Secular Music. Secular music. This is non-religious music. Travelling musicians called troubadours would go from town to town playing love songs. They learned their music by ear. Drums, harps, recorders, and bagpipes were popular instruments for these wandering musicians. This music was usually not written down. Sacred music. This is religious music. Most of the music of the early Middle Ages was written for the Catholic Church. Notation. During the Medieval period most music was not written down. Composers who did write their music down usually worked for the Catholic Church. Music notation appeared around the year 900, but it only showed the pitch. It didn´t tell you anything about the rhythm. A few hundred years would pass before the notes showed the rhythm. Bilingual Project. Music Department. I.E.S. López-Neyra.
