On the right bank of the Salzach River, near Mirabell Gardens, is the Mozarteum, Salzburg's major music and concert hall. All the big orchestra concerts, as well as organ recitals and chamber-music evenings, are presented here. In the old building at Schwarzstrasse, there are two concert halls, the Grosser Saal and the Wiener Saal. In the newer building on Mirabellplatz, concert halls include the Grosses Studio, the Leopold-Mozart Saal, and the Paumgartner Studio. Make sure to find out which hall your musical event is in. It's also a music school, and you can ask about free events staged by the students. The box office is open Monday through Thursday from 9am to 2pm and Friday from 9am to 4pm. Performances are at 11am or 7:30pm.
