Which annual classical-music event begins New Year's Day celebrations from Vienna's Musikverein?

The Vienna New Year's Concert begins New Year's Day celebrations from Vienna's Musikverein.

The concert is performed by the Vienna Philharmonic in the Musikverein's Golden Hall. Its program centers on music by the Strauss family, especially Johann Strauss II, along with works by related composers and occasional additions from other composers. The performance is broadcast internationally and has become one of the world's best-known classical music events.

The first concert in the series took place on December 31, 1939. From 1941 onward, the main concert was held on January 1, making it a New Year's Day tradition rather than a midnight New Year's Eve countdown. A conductor is selected for each edition, and the program changes annually.

The familiar closing sequence usually includes “The Blue Danube” and the “Radetzky March.” The audience traditionally applauds along with the march, although the concert's exact repertoire and presentation can vary.
