        Piano Tuning and Balancing Equations

        Examine how one innovator is working to improve the way concert pianos are designed and tuned. This video focuses on the balance that needs to occur in an ideally tuned piano key and explores how David Stanwood calculated the balance range through data analysis of measurements and ratios, taking math out of the classroom and into real world problem solving.
