Artist Luke Jerram wants to awaken Londoners from their humdrum daily routine and add a little music to the urban atmosphere. Jerram has had 30 pianos placed at well-known locations such as St. Paul's Cathedral, Millenium Bridge and the Liverpool Street Station. Called "Play Me, I'm Yours," the project is produced by a nonprofit called Sing London and City of London Festival. The pianos are intended for passers-by to perform impromptu recitals -- whether beginners or accomplished pianists -- anyone inclined to tickle the ivories. The instruments come complete with songbooks and are locked to the nearest bench or railing. They are also customized to fit their surroundings; at the Royal Exchange, for example, the piano has money printed on it.

Jerram has already pulled this off in cities from Sydney to Sao Paolo...perhaps coming to a city near you.
