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.

WEIGHT is the first mood created for this series and its main element is characterized by the quality of an object that reflects the force of gravity, and by which the earth attracts it.

The animated structure was designed as an array of suspended rocks and are repelled by the force created by its internal circular gravity. The sound recreates its movement and flows across the structure. This mood implies that the lowest frequencies are emphasized as the force which pulls the viewer in and out in the absence of it. It is often described as imparting depth to the sound, with weight and impact with solid, deep, and substantial sense of bass response.
