About

Edgar Berdahl is a leading researcher at the intersection of music, engineering, and human-computer interaction, best known for his pioneering work in actuated musical instruments and haptic feedback systems. His major contributions center on developing instruments that physically move and respond to a performer’s gestures, blurring the line between the physical and virtual in musical performance. In his highly cited 2011 article, "Advancements in Actuated Musical Instruments" (44 citations), Berdahl introduced an ecosystemic model of actuated performance, redefining how musicians interact with technology. He has also advanced expressively controlled percussion interfaces (2013) and force-feedback systems for shared human-robot control of virtual instruments (2012), where he implemented neural oscillator models to create more intuitive, gestural interactions. Berdahl’s work is notable for prioritizing expressive control over simple note triggering, offering new possibilities for performers and composers. His research has significant implications for interactive music systems, rehabilitation, and human-robot collaboration, making him a key figure in the emerging field of actuated musical interfaces.
