In Japan there is a growing business trend to play classical music to some food products like bananas, sake, noodles. For 20 years Ohara Shuzo, a sake brewery in Fukushima Prefecture, has been serenading their fermenting rice during the third stage of the brewing process. For an hour in the morning and one in the afternoon, maturing sake designated for the company’s “classical series” enjoys the vibrations of Mozart’s “Symphony 41” and “Piano Concerto 20” from their stainless-steal tanks. It wasn’t always this way. Experiments with jazz, Bach and Beethoven were initially conducted by the company, but they did not produce the “richer fragrance and a milder taste” that Mozart does, Ohara told the paper. While claims that music can benefit plants are nothing new, insisting the classical greats can improve the taste of everything from bananas to soy sauce certainly is. And it’s a growing business: Consumers in Japan can now pick up bananas, tomatoes, udon noodles and soy sauce that has a label on it saying that the product has been exposed to classical music of Mozart.
I think it's a great idea to sell something. It's a great way to differentiate the product from competitors. In the same time there have been studies made proving the effect of music. So, I as a consumer who believes in the power of the sound, would totally buy those products that are discussed above.
