scoreLight: a laser-based synesthetic experience


”scoreLight” is a playful musical instrument capable of generating sound from the lines of doodles as well as edges of threedimensional objects nearby (hands, dancer’s silhouette, architectural details, etc Fig.1). There is no camera nor projector: a laser spot explores the shape as a pick-up head would search for sound over the surface of a vinyl record with the significant difference that the groove is generated by the contours of the drawing itself. The light beam follows these countours in the very same way a blind person uses a white cane to stick to a guidance route on the street. Sound is produced and modulated according to the curvature of the lines, their inclination as well as their color and texture. This means that ”scoreLight” implements gesture, shape and colorto-sound artificial synesthesia [2,5]; abrupt changes in the direction of the lines trigger discrete sounds (percussion, glitches), thus creating a rhythmic base (the length of a closed path determining the overall tempo). In turn, the sound being generated affects both the kinematics and shape of the light spot, therefore forming an interesting audio-visual feedback. The result of all this is a spot of light that dances on the surface of the drawing, while singing its secret score. Figure 1: Contour guides the laser beam
