Landini, Francesco (fränchāsˈkō ländēˈnē) [key], c.1325–97, Italian composer. Although Landini was blinded from smallpox in childhood, he learned to play the lute, guitar, flute, and organ. His organ playing was highly regarded. Celebrated in his own day as a master of the Florentine ars nova style, among his works are madrigals, cacce, and ballate. His name was also spelled Landino.
