The 8-foot bridge has a flat top for the strings C - f1, with the strings resting on small pieces of wood perpendicular to the strings and with bridge pins on both sides, making the two strings of the course the same sounding length. Also the hitch pins are positioned side by side so that the string lengths from tangent to hitch pin are the same.

This construction can be seen also in X5488 (Johannes Broman, 1763). That instrument had a Pythagorean string scale according to the ideas presented by the Royal Swedish Academy of Science, but this clavichord has a traditional scale.
