The concept is fairly simple: our Doutreligne pianos and grand pianos are set up temporarily or even permanently in places where many people pass by. Music then not only eases the waiting, it also creates a more enjoyable atmosphere.
Places like train stations, airports, hospitals, shopping centres, libraries, city parks, and so on. The piano is a robust instrument, which passers-by may happily play: 'No touching' is out of the question, so to speak. And the instrument gets so much respect from passers-by that few, if any, problems or vandalism are observed.
On the contrary: hundreds of pianists play there every day, from amateur pianists to professionals who happen to pass by. They often provide unforgettable moments. Look at all the YouTube videos that go viral, sometimes showing entire musical groups or choirs giving an "on the spot" performance before taking the train or plane.
