There are two girls and two guys. The guys are not who they appear to be. Nobody is sure who is pairing off with who and there’s a scheming servant. And we are in Naples. You know the opera of course. It’s Rossini’s L’occasione fa il ladre. It’s one of Rossini’s early one act farsi for La Fenice and it’s quite good, if very silly. There are plenty of musical high jinks with fast paced ensembles and some wicked coloratura. And it has an unambiguously happy ending. You will also likely recognise some of the music as, in best Rossini fashion, he used chunks of it in later works.
There are some seriously obscure Rossini operas and Il signor Bruschino is one of them. It’s scarcely an opera at all really. It’s a one act farsa running about an hour and a quarter. By the time he wrote this one at age twenty Rossini has already had several hits in the genre and knew how to pull out a crowd pleaser but oddly Il signor Bruschini was a colossal flop. The plot was too convoluted and the music too advanced for the tastes of the farsistas. If one wanted to think about the plot one went to a proper opera house like La fenice rather than the fairly obscure Venetian theatre where the work premiered. It even offended the critics by, horror of horrors, asking the second violins to tap on their music stands with their bows during certain passages of the sinfonia.
