  Medieval music includes Western European music from after the fall of the Western Roman Empire by 476 to about 1400. Monophonic chant, also called plainsong or Gregorian chant, was the dominant form until about 1100. Christian monks developed the first forms of European musical notation in order to standardize liturgy throughout the Church. Polyphonic (multi-voiced) music developed from monophonic chant throughout the late Middle Ages and into the Renaissance, including the more complex voicings of motets. During the earlier medieval period, the vocal music from the liturgical genre, predominantly Gregorian chant, was monophonic, using a single, unaccompanied vocal melody line. Polyphonic vocal genres, which used multiple independent vocal melodies, began to develop during the high medieval era, becoming prevalent by the later 13th and early 14th century. Notable Medieval composers include Hildegard of Bingen, Léonin, Pérotin, Philippe de Vitry, Guillaume de Machaut, Francesco Landini, and Johannes Ciconia.
  
  Many medieval musical instruments still exist, but in different forms. Medieval instruments included the flute, the recorder and plucked string instruments like the lute. As well, early versions of the organ and fiddle (or vielle) existed. Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut (loud, shrill, outdoor instruments) and bas (quieter, more intimate instruments). A number of instrument have roots in Eastern predecessors that were adopted from the medieval Islamic world. For example, the Arabic rebab is the ancestor of all European bowed string instruments, including the lira, rebec and violin.
