Wherein a cajon incorporating a rattle system is attached to the front panel of the cajon, provision is made that the rattle system give off a more desirable musical rattle or buzzing sound then any prior art as the cajon is played by a percussionist. With the rattle system mounted and in place, it's hollow body allows free moving glass beads to be set into motion creating a much desired audible response upon impact of the front face of the cajon. Further, this audible response is a controlled or gated response due to the way the glass beads travel up an incline within the rattle assembly and then return to their relative starting positions leaving no lingering rattle or buzzing sound.
