Abstract:
This invention relates to a musical instrument, specifically a frame cajon comprising a cuboid frame with structural surfaces on the top and bottom that completely support the weight of the player allowing multiple playable sides to be attached for the percussionist. Two of the sides are further partitioned to produce a high and low pitched tone. Where a raspier tone is desired, snare wires are strung vertically between top and bottom horizontal members of the frame. The vertical members on each side of the snares are slightly concave to gently engage the snares with the playing surface. One side has a 16″ drum head mounted for playing, resonance, and tuning the cajon. The cajon is raised a minimum of two and a half inches on casters or by other means to acoustically decouple the cajon from the floor to improve tone and clarity.
