 Trecento music influenced northern musicians such as Johannes Ciconia, whose synthesis of the French and Italian styles presaged the "international" music typical of the Renaissance.During the 15th century, Italy entered a slow period in native composition, with the exception of a few bright lights such as the performer and anthologist Leonardo Giustinian.As the powerful northern families such as the d'Este and Medici built up powerful political dynasties, they brought northern composers of the Franco-Flemish school such as Josquin and Compère to their courts.
