[email protected] On the input admittance of many violins a typical broad frequency peak, called "bridge hill" appears around 2.5 kHz. The physical parameters of a violin bridge have a significant influence on this feature, and then on the tonal colouration of the produced sound. The effect of the bridge characteristics (mass, stiffness and foot spacing) on the frequency response have been revealed by using bridge models through several studies.
