Domenico Cimarosa’s most successful opera, The Secret Marriage, was composed on a libretto written by Giovanni Bertati, a Venetian employed as court poet in Vienna, on a subject very popular at the time. The story was in fact at the centre of a series of 6 paintings by William Hogarth, the Marriage in Fashion, le Mariage à la Mode, published in London between 1743 and 1745, depicting the bad consequences of a wedding between a penniless aristocrat and a rich bourgeois. Bertati the librettist turns the social satire into a mockery of bourgeois, eager to ennoble but happy to save half of the dowry when the opportunity arises.
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.
Locked in my room, I recite the characters’ parts passionately and study my voice: its inflections, the tempo and pauses, in short the emphasis a man uses when he’s at the mercy of his passions. I then identify the right tempo and melody in order to allow the singers to express those passions by the means of harmony. I put the ideas on paper, try them on the harpsichord. When I feel the same emotion I wanted to express I judge I have succeeded; if I don’t, I look again for inspiration until I feel I’ve achieved my goal”.
Vincenzo Gonzaga, Duke of Mantua attended the successful performance of Peri’s Euridice in Florence, which was probabily witnessed also by Monteverdi himself. The Duke realized immediately the originality of this new entertainment and the prestige that would reflect on the lord that sponsored it.
