A percussion musical instrument includes a first support frame for holding one group of tone bars and a second support frame for carrying another group of tone bars. The second support frame has both of its longitudinal ends connected rotatably to the corresponding longitudinal ends of the first frame in such a manner that the tone bars carried on the second support frame are made collectively to rotate between the first position horizontally aligned with the tone bars of the first support frame and the second position where the tone bass of the second support frame spatially face those of the first support frame, whereby the instrument can be easily set in the first position for performance and to the second position convenient for the whole musical instrument to be carried by the player himself.
