The main difference between Opera and the previous polyphonic vocal music is the unique melodic line, resulting from the merging of bass and singing. In polyphonic music different vocal lines work independently, overlapping one another and making a text often incomprehensible. Opera instead offered a new way for making words expressive and intelligible, by creating a single melodic line, supported by an accompaniment.
The Teatro San Carlo, certainly one of the finest and biggest in Europe was opened in 1737. Two years later, in 1739 French politician and writer Charles de Brosses referred to Naples as “the world capital of music”.
Opera is a drama created through music. It is the result of the joint effort of some of the best poets and composers in music history who worked together in perfect synergy to create a work as a whole.
Venice was an important and rich commercial centre, welcoming foreign merchants, businessmen dignitaries and aristocrats on the Grand Tour. The demand for entertainment was therefore high, particularly during the Carnevale, Some enterprising impresarios came up with the idea of setting up a public opera house, charging the public for the hire of boxes on a subscription system. The business turned out to be profitable. In a few years 16 theatres were built requiring a big number of new operas. By the end of 1600 the repertoire counted about 300 operas.
