How is the repertoire of Vienna New Year Concert determined?

The repertoire of the annual Vienna New Year Concert is decided by the conductor of the year and the musicians of the orchestra (mainly the chief conductor and the orchestra manager).

But we can still see the elegant demeanor of this powerful conductor in the annual repertoire: for example, the repertoire of 1987 Vienna New Year Concert is karajan's best work, and he has conducted many times. Muti's repertoire is often very unusual. Josef strauss's two Mazupaca Polkas often appear in Mehta's repertoire list. Ma Zeer likes Johann Strauss II's "The Story Waltz of the Vienna Forest" and "Mazupaca Polka Dance with One Heart and One Mind". Pratt's repertoire list is bound to include works involving French style, and so on. These characteristics are obvious to all.

Therefore, we can see that in the process of selecting songs every year, the opinions of the conductor often play a leading role, while the orchestra usually plays the role of proposing amendments.
