Thomastik-Infeld Dominant Rosin for Violin / Viola / Cello Ortega Developed through research and experimentationA natural rosin processed to optimize the performance of synthetic core strings. Made from a delicate blend of refined resins and exotic wax, Dominant Rosin provides the exact friction needed to promote the ideal torque based vibration of any synthetic core violin or viola string.
