Geology Lesson: Ringing Rocks

Dionn Renee

We begin with Dr. Brett McLaurin, Professor of Environmental, Geographical, and Geological Sciences at Commonwealth University, who helps us understand why certain rocks can sing. Using the famous ringing rocks of Bucks County as a starting point, Dr. McLaurin explains how mineral composition, cooling rates, and internal stress create boulders that chime like bells when struck. From Pennsylvania to sites around the world, these “lithophonic” rocks reveal surprising truths about Earth’s processes — and why some landscapes literally hold their own music.

Then we shift from geological resonance to human resilience with international fine artist Dionn Reneé, a Harrisburg native whose original artwork was selected for the global marketing campaign of Sony’s The Woman King, starring Viola Davis. Dionn shares how her lifelong battle with lupus, her commitment to fitness and MMA training, and her deep connection to the film’s themes shaped her artistic approach. Her work — celebrated across the entertainment industry — reflects the same warrior spirit that defines the story on screen
