This is series 1 of our 'Music Through the ages' listening diary, where every week we will focus on listening to samples of music from that particular time period. This week it is Medieval Music. Medieval (500–1400) Music at this time was heavily influenced by the growing power the Church began to wield, and notation was reintroduced into the musical repertory, a major distinction from earlier songs. Unfortunately, much of the music of this time was destroyed. We do have several medieval liturgical pieces from Roman Catholic Church. The Gregorian Chant is one of the most famous pieces from this era. Characteristics Of Medieval and Early Renaissance Music: During the middle ages, musical texture was monophonic, meaning it has a single melodic line. Sacred vocal music such as Gregorian chants were set to Latin text and sung unaccompanied. Four of the most important composers from the Medieval Period were Hildegard von Bingen, Leonin, Perotin, and Guillaume de Machaut.
