to the whole street. Encourage stewards and a shared pride of ownership. Plan for small rewards (a few flowers from the local shop, donated?) that you can send to stewards to let them know they are valued. Plan a launch event -- start a month prior to your piano's launch by contacting local media and your community partners. Launch and enjoy. Music draws people. The positive energy that flows from seeing people enjoy themselves in public is invigorating and contagious.
