Philharmonia Zurich is the orchestra of Zurich Opera. As an independent body of 116 contract players, it has existed since 1985 under the name of Zurich Opera Orchestra. It was renamed in 2012 with the appointment of director Andreas Homoki and general music director Fabio Luisi.
History
The history of Philharmonia Zurich is closely linked to that of Zurich's Tonhalle Orchestra. Opera has been performed in Zurich since 1834, at first in the Aktientheater at Untere Zäune, Zurich's first permanent theatre, until it burned to the ground on New Year's Eve 1890. Richard Wagner conducted in the Aktientheater in the early 1850s, including the first performance of The Flying Dutchman and of Tannhäuser. For his own productions he augmented the orchestra, on one occasion from 30 to 70 players. In 1851 Wagner wrote an essay entitled 'A Theatre in Zurich', in which he outlined his suggestions for the reform of Zurich's musical life, although at first none of them could be implemented. In 1853 he directed the first Wagner-Festspiele in the Aktientheater within the framework of the Allgemeine Musikgesellschaft (General Music Society) in Zurich.

The Orchesterverein, Zurich's first permanent professional ensemble, was founded in 1861. The 31 musicians played for the Allgemeine Musikgesellschaft (in the Kasino, now the Geschworenengericht) and for the Aktientheater. In 1867 the Schweizerisches Musikfest took place in Zurich, and for this purpose the old Kornhaus (Corn Exchange), on the site of today's opera house, was converted into a concert hall. In 1868 the Tonhalle Gesellschaft (Tonhalle Society) was set up and took over the running of the orchestra from the Allgemeine Musikgesellschaft.

In the Grosser Tonhalle-Saal, its new concert hall built in 1895, the orchestra achieved distinction under the direction of its first Chief Conductor, Friedrich Hegar and his friend Johannes Brahms. An intensive collaboration with the composer Ferruccio Busoni followed under Chief Conductor Volkmar Andreae. At the Stadttheater, built in 1891, artistic personalities like Richard Strauss and the young Wilhelm Furtwängler determined the orchestra's progress. Richard Strauss conducted and attended many performances of his own stage works in Zurich. Several first performances of works by composers ostracised in Germany and Austria by the Nazi regime took place in Zurich's Stadttheater, such as Alban Berg's Lulu (1927) and Paul Hindemith's Mathis der Maler (1938). Many other significant operatic works of the twentieth century were also premiered at the "Opernhaus Zürich", as it has been known since 1964. The Zurich Stadttheater was also one of the leading houses in the field of operetta, particularly during the period of discrimination against numerous Jewish composers of this genre, such as Ralph Benatzky, Oscar Straus, Paul Abraham and Emmerich Kálmán.

In 1944, the Schweizerische Rundspruchgesellschaft (Swiss Broadcasting Corporation) dissolved its Zurich-based radio orchestra. Thanks to an initiative of the mayor of Zurich at the time, Adolf Lüchinger, the entire radio orchestra was incorporated into the Tonhalle Orchestra from 1 December 1944. The 142-strong orchestra was divided into concert and theatre formations, and was known from then on as the Tonhalle- und Theaterorchester TTO Zürich. In 1946 the first woman was awarded a permanent position in the violin section. By 1968 there were fifteen female musicians. There followed contractual regulation of working conditions (collective labour agreements 1947, 1954, 1965) and of the orchestral work distribution between the Tonhalle Gesellschaft and Theater AG, and the establishment of an orchestral management and joint committee.
Highlights in the history of the theatre branch of the TTO were the Monteverdi and Mozart cycles begun in the 1970s with Nikolaus Harnoncourt (Musical Director) and Jean-Pierre Ponnelle (Stage Director). Further influences on the Opera House orchestra were conductors such as Ferdinand Leitner (Chief Musical Director at Zurich Opera House from 1969 until 1984) and Nello Santi (Musical Director from 1958 until 1969, and regular guest conductor ever since).
Managerial staffing difficulties and the century-old wish of the Tonhalle Gesellschaft and Zurich Opera House for independent programming led in 1985 to the rescission of the articles of association of both institutions and to the splitting of the TTO into the Tonhalle Orchestra and the Zurich Opera Orchestra. This split occurred at the same time as the renovation of the Opera House in 1984 and the preceding heated cultural and political debate in Zurich, which had led to disturbances by young people in the city in 1980.
