摘要

The device has twelve sound generators e.g. metal or wooden disks, attached to a cycle of fifths shaped arrangement in a round wooden plate for forming a roulette-like rotating circular structure. The wooden plate is embedded in a play board e.g. parlor play board, and the sound generators produce sounds of different lengths. Four players sit around the play board and beat the sound generators with sticks for producing twelve different tones.
