I Capuleti e i Montecchi is considered by many Bellini’s first masterpiece. It certainly recalls in many ways the great belcanto era, particularly in the way the roles are organized: the mezzo-soprano as male protagonist, the soprano as his lover, the tenor as the hero’s rival, bass and bariton respectively as the noble father and the tyrant. However, Capuleti is not strictly a belcanto opera because of its intimate and at times dramatic atmosphere. So much so that the many embellishments, counterbalanced by a well-defined melodic core, are not ornamentation anymore but start to take an expressive connotation.
Opera, until then the favourite entertainment of aristocracy and educated classes, was going to change radically as a consequence of the French revolution. In the three decades of the rise and fall of Napoleon, opera social function changed completely and irrevocably.
