Based on a scientific study, where it was proven that, if several people sing the same song simultaneously, their heart mark the same rhythm, LaLiga formed a choir made up of 42 real fans from all the clubs to carry out an experiment with its own soundtrack, directed by its compositor, Lucas Vidal. And through technology developed especially for this experiment , which monitored their heartbeats, we were able to prove that their heart rates were synchronised. The participants remained anonymous until the challenge was finished, when they discovered that they were all from rival teams. We proved that when we experience something together, it feels even greater.
