Tarja Ervasti: Colour music with Fractures

Interactive light art inspired by colour music, 2018

Colour music with Fractures is an interactive light art piece by Tarja Ervasti with contemporary music by Willie Budsko and a user interface designed by Jokke Heikkilä. It was first exhibited in MUU gallery (2018) and Ateneum Art museum, Helsinki (2019).

The artwork creates musical landscapes of colour and sound. The visual form of the piece alludes to the light organ, an instrument for playing colour music - an artform that is based on synaesthesia.

The work features lighting sequences created for seven compositions of about two minutes. Each music has seven alternative colour schemes, one chosen by the artist and others for the audience to play, according to their own sensibility of the music - colour relationship. The lighting sequences include colour schmes of red, green, blue, yellow, cyan, violet and white.

The materials of the artwork are a frame structure of black polycarbonate, a back projection screen, lighting instruments hung on a truss system, LED light balls with motors, two intelligent moving lights, audio and control systems and the user interface. All the materials belong to the artist except loudspeakers, truss system and moving lights, which should be rented on site.
