MUSICAL COMPOSITION.
A very valuable musical manuscript, by Guillaume de Machault, who was valet de chambre to Phillippe-le-Bel, in 1307, has been discovered in the royal library at Paris. It contains several French and Latin anthems, ballads, &c.; and concludes with a mass, which is supposed to have been sung at the coronation of Charles V., in 1364; and which proves, at that time they were acquainted with the art of composition in four parts.
