Abstract: The adjustment of the distance between clamping elements (13, 14) of a shoulder rest for violin or the like instrument is effected by a stem-like fastener, preferably a thumbscrew (37) passing through one of generally equidistantly spaced apart openings (29, 30) in a foot member (17) and through that opening (29, 30) which is aligned with one of at least two nuts (33, 34) embedded in an elongated base (10) of the shoulder rest.According to the invention, the longitudinal spacing between the openings (29, 30) differs from that of the nuts (33, 34) preferably such that one spacing is one-half of the other, whereby a fine adjustment of the clamping distance can be achieved, while the number of the nuts (33, 34) and/or the openings (29, 30) is relatively small, in the embodiment shown, two of each, permitting a total of four different adjustments of the clamping distance.
