SHARPNESS is an audio-visual sound sculpture released as part of MOOD E-LEV-EN, a collection of five works by Francisco Telleria.

MOOD E-LEV-EN is an ongoing study started in 2020, which explores the emotions derived from grounded cognition perspective and how they are affected by the perception of the virtual space, music, and spatial soundscapes. To achieve the study, Francisco Telleria designed eleven interactive 3D environments, characterized by 11 grounded cognition perspectives which are defined as follows: Weight, Sharpness, Smoothness, Moisture, Temperature, Movement, Spatial Height, Mass, Strength, Brightness, and Thinking. Each 3D environment is structurally represented by its physical and audio properties, as well as its animation which is performed by reacting to Francisco´s original music or soundscapes across the piece. This collection presents the first five out of eleven virtual abstract spaces in the series.

In SHARPNESS, the movement of light within the frame of the structure creates lines that turn into triangles and the illusion of sharp edges that can dance within its constant circular moving stage. The associated trembling music piece created by Francisco Telleria dictates the evolution of the light and a change in its behaviour. The combinations of these sound properties are used to illustrate the perception of objects that defines their pulses across the sharp environment, and it gives rise to the experience of contrasting meaning among the surfaces.
