The ladder transforms into a giant piano keyboard!!!

These inspiring and innovative installations are interactive so that the notes of the song or melody are played at every turn. They are also called social ladders. They can be applied to any stairs. The ladder transforms into a giant piano keyboard in a non-invasive way. Several piano ladders have been installed in shopping malls, metro stations, museums and science centers in different cities.

Piano stairs play melody notes or piano tones when people walk on them. These works of art encourage people to take the stairs instead of the elevator or escalator. Musical ladders change people’s behavior for the better (health), making them fun. In other words, physical activity is encouraged when climbing stairs is fun. The study showed that passengers prefer to take the stairs with the piano 66% more often than the escalator. They can also be used to create public spaces to attract people.
