GSM recreate the sounds of stalactites during an exhibition Gibraltar

In 2019, the Global Sound Movement (GSM), a non-profit organisation affiliated with the University of Central Lancashire, embarked on an innovative project in Gibraltar's St. Michael's Cave. Their mission was to capture the unique acoustic properties of the cave's stalactites and stalagmites, transforming these natural formations into a virtual lithophone—a musical instrument made from resonant stones.

The GSM team recorded the sounds produced by striking the stalactites, capturing the reverberations within the cave's limestone chambers. To enhance the auditory experience, they also collected environmental recordings from various locations around Gibraltar, including the Moorish Castle and World War II tunnels. This comprehensive approach allowed them to digitally recreate how the stalactites' sounds would resonate in different settings across the Rock.

The culmination of this project was the "Hidden Melodies" exhibition, held at the Magazine Studio Theatre in Gibraltar. Visitors engaged with an interactive soundboard, enabling them to compose music using the stalactite samples and experience the distinct acoustics of various Gibraltar landmarks. This immersive installation offered a unique opportunity to explore the hidden sounds of the Rock, fostering a deeper appreciation for Gibraltar's natural and cultural heritage.

Through projects like "Hidden Melodies," GSM continues to bridge the gap between natural acoustics and digital technology, preserving and showcasing the world's unique sonic landscapes for future generations.
