The concert hall is the largest room in the museum. In addition to various types of keyboard instruments from the 17th to the 20th century, there are also harps, viols, an Austrian Baroque organ dating back to around 1670, and an Italian theorbo (bass lute) bearing the signature of the Venetian maker Magnus Tieffenbrucker. The walls are adorned with portraits of composers and music personalities. Here, one can also observe a choral score from the first half of the 17th century, where the entire choir can read from the same book. The piece is a Matteuspassion by Giovanni Rovetta (ca. 1595-1668). In the concert hall, well-received chamber music concerts are regularly held.
