Have you ever looked at a map and wondered what it would sound like if its data could play a melody? Maps are usually silent, yet behind their colours and shapes lie rhythms, variations, and patterns that describe how the world changes over time. From population growth to air pollution, from ocean temperature to migration, every dataset tells a story — and when transformed into sound, those numbers can become music that helps us “hear” the pulse of our planet.

Sonification is the process of converting data into sound. Scientists and artists have used it to represent phenomena that are difficult to visualize, such as gravitational waves, climate variations, or even solar activity. By assigning different data values to elements like pitch, rhythm, or volume, it becomes possible to translate complex information into an auditory experience. This multisensory approach can reveal hidden trends and allows learners to interpret information in a creative and emotional way, merging science and art.
