Hucbald

thumb|Hucald's Musica, page 125 in the Codex 169(468) from the Abbey library of Saint Gall Hucbald ( – 20 June 930; also Hucbaldus or Hubaldus) was a Benedictine monk active as a music theorist, poet, composer, teacher, and hagiographer. He was long associated with Saint-Amand Abbey, so is often known as Hucbald of St Amand. Deeply influenced by Boethius' De Institutione Musica, Hucbald's (De) Musica, formerly known as De harmonica institutione, aims to reconcile ancient Greek music theory and the contemporary practice of Gregorian chant with the use of many notated examples. Among the leading music theorists of the Carolingian era, he was likely a near contemporary of Aurelian of Réôme, the unknown author of the Musica enchiriadis, and the anonymous authors of other music theory texts Commemoratio brevis, Alia musica, and De modis.

==Life== Born in northern France, about 840 or 850, Hucbald studied at Elnone Abbey (later named Saint-Amand Abbey, after its 7th-century founder) where his uncle Milo was chief master of studies (scholasticus), in the diocese of Doornik. He made rapid progress in the sciences of the quadrivium, including that of practical music, and, according to a laudatory 11th-century biographical account, at an early age composed a hymn in honour of St Andrew, which met with such success as to excite the jealousy of his uncle. It is said that Hucbald in consequence was compelled to leave Saint-Amand and to seek protection from the bishop of Nevers.
