The 54 steps in Wulin Plaza, China, resemble black and white keys and play different notes when stepped on.
These piano stairs were created to encourage people to choose the healthier option of walking up the steps instead of riding the escalator at Wulin Plaza in Hangzhou, China.
The 54 steps look like the black and white keys of a piano and play the different relevant notes when stepped on. So people walking up and down them can create their own musical melodies. You can watch a video of the piano stairs by SINA English below:
