Vienna Philharmonic roots
The first floor gives Seilerstätte its historical charge. Otto Nicolai, founder of the Vienna Philharmonic, lived in the Palais Erzherzog Karl from 1841 to 1847, and the archive displays objects tied to the orchestra's early story, including the founding decree and the first concert poster from March 28, 1842.
Sonotopia and sound physics
On the sound-science floor, Sonotopia turns acoustics into something you can feel. You move from hearing experiments to oversized instruments and sound creatures, so abstract ideas like waves, ears, and vibration become physical rather than textbook-heavy.
Composer rooms and Namadeus
The composer floor brings Haydn, Mozart, Beethoven, Schubert, Strauss II, Mahler, and later Viennese voices into one route. Namadeus is the playful reset: your name becomes a small composition inspired by a musical game linked to Wolfgang Amadeus Mozart.
Virtual conductor and Stairplay
The Virtual Conductor is the museum's comic-triumphant finale: you lift the baton and the projected Vienna Philharmonic reacts. On the way, Stairplay turns the historic staircase into a piano-like sound path, which is exactly the kind of Vienna memory children remember later.
