HUCBALD (HUGBALDUS, HUBALDUS) (c. 840-93o), Bene dictine monk, and writer on music, was born at the monastery of Saint Amand near Tournai. He studied at the monastery, where his uncle Milo was head of the school. Hucbald's success in music is said to have excited his uncle's jealousy and to have made it necessary for him to leave St. Amand. In 86o he was at St. Germain d'Auxerre, bent upon completing his studies, and in 872 he was back again at St. Amand as successor to his uncle, to whom he had been reconciled in the meantime. Between 883 and 90o Hucbald went on several missions of reforming various schools of music, including that of Reims, but in 90o he returned to St. Amand, where he died on June 25, 93o, or, according to other chroniclers, on June 20;932. The only work which can positively be ascribed to him is his Harmonica Institutio. The Musica Enchiriadis, published with other writings of minor importance in Gerbert's Scriptores de Musica, and containing a complete system of musical science as well as instructions regarding nota tion, dates from the close of the loth century. This work is cele brated chiefly for an essay on a new form of notation described in the present day as Dasia Notation. The author of the Har monica Institutio wrote numerous lives of the saints and a curious poem on bald men, dedicated to Charles the Bald.
