In a keyboard musical percussion instrument having a series of tone bars mounted to at least first and second, spaced-apart support rails, each tone bar having a body with first and second nodes of its fundamental mode of vibration (Node A and Node B), Node B being spaced from Node A along a longitudinal axis of the tone bar body, and the body defining a bottom surface and a mounting hole formed in the bottom surface at Node A, a tone bar suspension assembly for mounting a tone bar includes first and second suspension bumpers extending from the first support rail and having upper suspension surfaces to engage the bottom surface of the body at spaced apart locations in a plane generally transverse to the longitudinal axis of the body at Node B, and a suspension pin extending from the second support rail to engage in the mounting hole. A keyboard musical percussion instrument employing the tone bar suspension assembly, and methods for mounting a tone bar and adjusting tone bar ring time are also described.
