That’s high classical—Mozart, Beethoven, and Schubert—but there is also the waltz, the Waltz King, and “The Blue Danube.” On our second day in Vienna, which happened to be Halloween day, we visited the Haus der Music, a modern, high-tech museum devoted to the history and science of Viennese music. We rolled dice—Joe threw the red die and I threw the blue one—and a giant screen made aleatory music out of the results. The composition wasn’t half bad, either. Then we let Mozart write music based on the spelling of our names. He seems to have composed a brief phrase for every letter of the alphabet, and the results could be played back in their original form or orchestrated. And that was just the first floor.
We had been spiraling higher and higher in the Haus der Music, and by the time we took the elevator back down to the ground floor, night had fallen. Halloween night. The nice people at the ticket desk were all wearing costumes, and the large ground-floor room was filled with children, little girls dressed as witches, little boys dressed as skeletons. Time for us to waltz out the door and look for a place to have dinner.
