Tuned Stairs

As visitors walk down stairs leading to an exhibition, their footsteps activate a musical sound. The installation refocuses the attention of the visitor onto their footfalls – allowing them the opportunity to compose their timing, movement, and the resulting melody.

On each of the stairs is a matt-switch which activates the instrument-playing mechanism attached on the outside of the banister. The armature is made of steel with a pull-thust solenoid attached to it. Above the solenoid is a tuned resonating bar facing down. As the matt-switch is activated, the solenoid momentarily strikes the resonating bar – resulting in a soft delicate sound resonating through the local area. The matt-switch’s signal gets fed into an arduino board which then activates the solenoid mechanism through a transistor circuit. Each arduino has its own conduit board built to easily connect the switches to their corresponding solenoid mechanisms.
