Il signor Fagotto is a one-act opérette by Jacques Offenbach to a French libretto by Charles-Louis-Étienne Nuitter and Étienne Tréfeu, first performed in 1863.
[2] The work was premiered by Offenbach’s company at Bad Ems, before transferring to the Théâtre des Bouffes Parisiens, Rue Monsigny, Paris, a few months later, where it enjoyed several revivals.
The work was performed in a revised form in Vienna shortly after the premiere of Die Rheinnixen in 1864 and dedicated to Eduard Hanslick.
Bertolucci's servant Bacòlo spots an opportunity for him to win the heart and hand of Moschetta, who has spurned him so far, by assisting with a plot to outwit their master and musical snob.
Fagotto appears wearing an eccentric costume; he then displays some especially gymnastic skills and his talent in imitative music including animals and fireworks.
