The sounds coming out of the Rockhal on Sunday were surprisingly discordant. National Research Fund (FNR), Uni and Luxembourg Institute of Science and Technology brought science and music together there for the launch of the project “The Sound of Data”.

While the adults listen to experts in the club, in the foyer, the families watch the lightning pulse to the rhythm of music, the children create geometric figures in the sand by modifying the frequency which passes through a vibrating plate… make the sounds visible”, notes Pascal Waechter, scientific mediator. “We see how music is physics, appreciates Alec, 39. I was interested in a software that I use to make music”.

He came with his boys. “At 3 and 5, they are too young to understand, but find it very amusing”. “The goal is to create a madeleine of Proust, says Pascal Waechter, when they are university students, they will remember these experiences”. Robert, 38, is there with his family because his teenage daughter “is interested in electro music. It’s a good way to see what’s behind it.”

More broadly, “The Sound of Data” is interested in “sonification, the fact of transforming data into music. We created sound with Covid data from Statec”, explains Patrizia Luchetta, from the FNR
