In a brass musical instrument having two substantially parallel adjacent braces between portions of the instrument windpath tubing, the improvement comprising a cross-brace extending in planes substantially parallel to a plane of the parallel braces and having two opposed edges each with two spaced contact regions secured to a respective one of the parallel braces and a recessed region between the contact regions, thereby allowing elimination of other windpath bracing and providing a beneficial site for sound-modifying components.
