Terrasonica is the sound project of Vera Cavallin, a musician and curator. Launched in 2024 with the support of the Culture Moves Europe funds from the Goethe Institute and the European Commission, terrasonica began as a vision to craft a soundscape journey on the island of Favignana, Sicily. Its goal was to uncover the island’s acoustic universe for curious onlookers, tourists, and travelers. The project’s first achievement was the creation of a sound map of Favignana, which paved the way to this website's launch. In the evolution of the work, terrasonica continued to design sound walks in remote locations, capturing their unique soundscapes. These recordings became a way to reflect on the beauty, complexity, and significance of the sounds surrounding us. However, through these journeys and careful observation, a deeper awareness emerged. Many places are losing their distinctive sounds. Entire natural soundscapes are fading, threatened by environmental change and human activity, leaving future generations at risk of never experiencing them. With each voyage, terrasonica builds a library of sounds that are disappearing or undergoing significant transformations—a repository of auditory heritage. This growing collection offers food for thought and a chance for discovery, an invitation to travel, listen, and act.
