The House of Music is an interactive sound museum with four floors. The Vienna Philharmonic Museum is located on the first floor. The second floor, "Sonotopia," is dedicated to sound phenomena – here you can experiment with different sounds and learn a great deal about sound, hearing, and instrument groups. On the third floor, "Viennese Classicism," you'll discover everything you need to know about the most famous composers (Mozart, Beethoven, Schubert, etc.) who lived and worked in Vienna. The fourth floor houses the popular Virtual Conductor and the House of Music Museum Shop.
