Denoted Structures is an interactive sound installation by Oliver Wilshen developed during studies at the University of Brighton and as part of a BA Hons in Music and Visual Art. This piece consists of suspended sections of a dismantled upright piano, equipped with mechanical hammers and motors, allowing audience interaction through touching the original piano keys. The work is based on the accumulation of research into combining that of the pure and precise alongside the organic and irregular.

The piano frame and its keyboard were chosen as due to it’s ability to adapt and respond to evolving technologies throughout the last 300 years. From the plucked strings of the harpsichord through to the electric circuitry of organs and midi signalling of digital pianos, the keyboard has proved to be an enduring interface for the expression of human emotion and thought through sound and music.
