Hello Stockholmer! Stockholm is soooo Cool! Just came across piano stairs on the subway stairways on Odenplan, Stockholm. And to our surprise, Stockholmers are musician in nature I think? Most are prefer to use the piano stairs rather than elevator stairs.
The video above shows what happens when a staircase is converted into a working piano where each step is a different piano key that makes a sound when you step on it.
What if we put it on the shopping complex on our hometown? Would that be something unique?
