L'incontro improvviso

The libretto by Karl Frieberth was adapted and translated from a French opéra comique by L. H. Dancourt, already set by Gluck in 1764 as the La rencontre imprévue. In keeping with Italian practice, Friberth constructed longer buffo finale texts at the end of Acts I and II. It is not known if any further performances followed the Eszterháza production, although a German translation was made for Bratislava. Danish musicologist Jens Peter Larsen discovered the autograph score in Leningrad in 1954, and the opera was subsequently broadcast in Russian in 1956. It was first staged in the UK at the Camden Festival in 1966. The first complete recording was made by Philips in 1980 in association with the Radio Suisse Romande and the European Broadcasting Union, conducted by Antal Doráti. The first performance of the German translation was staged by Jakob Peter-Messer for the Wuppertal Opera in 2010 in cooperation with the Haydn-Institut in Cologne. ==Roles==

Overture (this was printed by Artaria in a set of six in 1782 without trumpets and percussion) Act I A storehouse of all kinds of merchandise and edibles The qalandar and dervishes drink wine, smoke tobacco and sing merrily of their life as beggars and tricksters. A square Osmin is distracted by the qalandar begging; he has little trouble in persuading the hungry Osmin to become a mendicant dervish. A room in the seraglio Rezia has been told that her long-lost love has been sighted in Cairo, and shares the news with Balkis and Dardane in a beautiful trio. A square Ali, alone, explains how he fled to Persia and fell in love with Rezia. Though betrothed to another, Rezia eloped with Ali but they were separated and she was captured by pirates. Ali watches as Osmin is taught by the Qalandar the chant "Castagna, castagna". The Qalandar recognises Ali as the Prince of Balsóra. Balkis greets Ali with news that a woman has espied him from a window in the seraglio and wishes to meet him. A room containing a banquet table Osmin is enjoying a feast with Ali arrives with Balkis, and Ali gets increasingly angry with Osmin's inebriation. Act II A room with a sofa Dardane tries to charm Ali to test his faithfulness. Rezia enters, taking Ali and Osmin by surprise. The three women tell of the unfortunate travels which brought them to Cairo. ''The qalandar's room'' Osmin informs the qalandar that Ali's lover is Rezia and solicits his help in letting the couple escape. A garden While preparations are made for a banquet before their escape, Rezia and Ali sing a love duet. The mood is shattered when Balkis and Dardane come in to announce that the Sultan has returned unexpectedly from the hunt. Everyone flees via a secret staircase. Act III ''Night. The qalandar's storehouse'' News of the Sultan's reward for the recovery of Rezia has reached the qalandar who decides to betray them to win the bounty. Ali disguises himself as a French painter to avoid arrest, but to no avail. The Sultan however forgives them and condemns the treacherous qalandar. A hall lit by chandeliers The Sultan pardons Rezia and Ali and gives them his blessing. At the couple's request the qalandar is pardoned, but banished from Cairo. ==Music==

Although not Haydn's greatest success in the operatic field, ''L'incontro improvviso'' does include some high-class and varied music. As well as the 'Turkish' music, amusing scenes for Osmin and Calandro, the 'painting' aria in the last act where Ali describes the contents of a picture with orchestral help, and another aria "Senti, al buio pian" for Osmin with orchestral colouring, there is Italian lyricism evident in arias for Ali ("Deh! se in ciel pietade avete") and Rezia ("Or vicina a te"). Act II has two powerful arias for sopranos; Haydn detached Rezia's "Or vicina a te" and published it separately in 1783. The Act I trio "Mi sembra un sogno,” which contrasts the three women’s voices with muted violins, cors anglais, and horns, is also considered a highlight. The work is scored for an orchestra consisting of 2 oboes (doubling cors anglais), 2 bassoons, 2 trumpets, 2 horns, timpani, percussion, violins I & II, viola, cello, bass and continuo. ==Recordings==
