The EMusic project aims to use music as a tool to explain, to a wide audience, the role of geophysics and geology in our society. By means of the sonification of the electromagnetic (EM) response of the Earth, we are able to accompany people on an imaginary voyage into the subsurface so that they can travel into the depths and into the past. In this way, the audience can learn about the geological evolution of the site, which is used as a natural stage, from where the EM data were collected.
