Symphony No. 3 (Beethoven) which the bass theme is heard as the first variation before the main theme ultimately appears. This again parallels the structure of the Opus 35 variations themselves. Finally, the loud E chord that begins the Opus 35 variations themselves is moved here to the beginning of the first movement, in the form of the two chords that introduce the first movement. Alternatively, the first movement's resemblance to the overture to the comic opera "Bastien und Bastienne" (1768), composed by twelve-year-old W. A. Mozart, has been noted. It was unlikely that Beethoven knew of that unpublished composition. A possible explanation is
Ivana Fišer Institute orchestra. As a conductor, Fišer debuted in 1933 while directing the comic opera Bastien und Bastienne with Zagreb philharmonic orchestra. From 1939 to 1941, she led the Zagreb Red Cross orchestra. Until 1941, she also led the Osijek philharmonic orchestra. From 1947 to 1965, Fišer worked as a prompter at the Croatian National Theatre in Zagreb. Ivana Fišer Ivana Fišer (born Fischer; June 13, 1905 – September 7, 1967) was known Croatian Jewish conductor. Fišer was born in Zagreb on June 13, 1905 to a Jewish family of well-known Croatian architect Ignjat Fischer and his wife Helena (née Egersrodfer).
