In the foyer of the opera house you can also look forward to the Musical Advent Calendar. From the 1st to the 23rd of December daily concerts take place there at 5.30 pm. The entrance to the short 15 minutes concerts is free to make the Christmas season more beautiful. Musicians of the Philharmonia Zurich, as well as singers of the Opernhaus, the International Opera Studio and the Choir of the Zurich Opera House, have developed an impressive program. The short concert programs are posted on their Facebook page.
