“Für Elise” is one of the world’s most widely-recognized pieces of music. The Beethoven melody has been played by pianists the world over, and its near-universal recognition has been used to attract customers for companies as big as McDonald’s and as small as your local ice-cream truck. But if you hear the song playing on the streets of Taiwan, accompanied by the low grumble of an engine, the only ice-cream you’ll find if you follow the tune will be the soupy remains of a neighbor’s Häagen-Dazs. In Taiwan, “Für Elise” means it is time to take out your trash. Directly out to the truck. Yourself.
