This is one of the most amazing videos I’ve ever seen. Those of you with babies (hint, hint, hint, and lord forgive me if I forgot anyone else’s child) might want to take note.
I apologize that the video is entirely in Japanese, with no subtitles.
Basically, this is a television show called Tantei Knight Scoop that documents strange and interesting people/places/things that their viewers often send in. In this episode, a mother of a child who fusses a lot writes in to say that a popular television commercial by Takemoto Piano has a strangely and instantaneously soothing effect on her son and his friends (this effect is in fact documented on the company’s website, and during the clip the man in the commercials says that people call in all the time asking when it will be on the air!). I think you can basically understand it from there. At the end of the show, the host concludes that the tonal range of the commercial is probably soothing to babies, at around 440 Hz.
Here are both commercials that reportedly make babies stop crying, rolled into a single clip:
Let me know if they really work or not!
UPDATE 2007/03/21: Once again, Takemoto’s tranquility effect transcends borders!
