I'll jump in here as a member of the NYC contingent and also agree with Harold completely . I would also add that Lachera's definition of The Wiener Philharmoniker is spot on , The Opera is the bread and butter work and admission to the Philharmonic is only extended after a three year probationary period . As far as what one indulges in at a performance , there are several things to be mindful of - Vienna is , evidently , one of the world class venues for " classical " music . " Classical " is usually used in a broad sense , not in the sense that " classical " refers to works of the period of Haydn and Mozart , that of the period of The Enlightenment . As music moves into later Beethoven , the style moves from classical to Romantic . My point here is that when choosing a performance , the choice should rest with the level of knowledge of the concertgoer . A novice listener who purchases a ticket to a concert of music by composers of " The Second Vienna School " might be confused and disappointed at a performance . When making a choice , knowledge of the program is essential . I am , as example , a Mahler fan , but Mahler is not everyone's cup of tea ( or coffee , since we are in Vienna ! ) . Insofar as the quality of performance is concerned , Vienna , like New York , has a large and highly skilled coterie of free lance musicians who staff the different venues , there is no room for substandard playing . Many of these free lancers comprise the Ballet and Volksoper as well as filling seats in The Staatsoper and Philharmoniker as required by large orchestrations ( Wagner and Richard Strauss operas , for example . So , the quality of performance at " Die Fledermaus " will be at the same high level as a performance of " Der Rosenkavalier " . It's really a question of what the auditor's tastes and desires are .
