Fundamental Interactions is a symphonic performance for spatialized orchestra, electronics, four screens, live video creation, and spatialized sound.

Through a fusion of sound and video, this performance examines the four fundamental forces—strong, weak, electromagnetic, and gravitational—that govern and balance the structure of the universe. These forces are responsible for all observable physical phenomena and interactions between particles.

Why do these four forces exist in the universe? While we do not yet know all the answers, this performance invites reflection on the mystery of these fundamental forces at the microscopic scale. Are they genuinely distinct, or could they be unified? Are we moving toward a “theory of everything”? Perhaps if the fundamental particles mediating these forces are linked, they might resemble “strings.” The day may come when the true origin of these interactions is understood.

During the performance, Yannick Paget conducts the N’SO KYOTO orchestra from within the ensemble, with musicians spread throughout the concert space. At the same time, he transforms the orchestra’s music into electronic soundscapes and performs percussion on a unique ceramic instrument created in collaboration with ceramic artist Toru Kurokawa.

Four surrounding screens display live video and creative visual effects—signature elements of N’SO KYOTO’s productions—enhancing the depth and impact of the performance. Together, these elements translate intricate physics concepts into a delicate and expressive musical form.
