Who ever would have doubted the good advice to whistle a happy tune and feel better?

Ai Kawakami from Tokyo University of the Arts did. And he has data to prove him right.

Mr. Kawakami and colleagues asked volunteers to listen to three pieces of music — two sad and one happy. They were asked to rate their perception of the music and their own emotional state.

It seems that participants felt happier when listening to sad music that they considered more tragic, less romantic and less blithe than they were.

Plus, sadness engendered by art can actually feel pleasant.

So when your hefty health insurance bill arrives or yet another fishing trip is rained out, forget Zip-a-Dee-Doo-Dah and try a dirge.
