Washington, DC Metro Station on a cold January morning in 2007. The man with a violin played six Bach pieces for about 45 minutes. During that time approx. 2 thousand people went through the station, most of them on their way to work. After 3 minutes a middle aged man noticed there was a musician playing. He slowed his pace and stopped for a few seconds and then hurried to meet his schedule.
The musician played continuously. Only 6 people stopped and listened for a short while. About 20 gave money but continued to walk at their normal pace. The man collected a total of $32
*No one knew this, but the violinist was Joshua Bell, one of the greatest musicians in the world. He played one of the most intricate pieces ever written, with a violin worth $3.5 million dollars. Two days before Joshua Bell sold out a theater in Boston where the seats averaged $100.
This is a true story. Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of a social experiment about perception, taste and people's priorities*
