  • Patent number: 4061337
    Abstract: A game is provided having educational and entertainment value with regard to music. The game includes a game board having spaces providing a path of movement for a game piece about the periphery of the board. Each movement of the game piece is determined from instruction cards placed face down on the game board in separate stacks each covered by a control card visibly depicting a different musical note. The game further includes chance cubes each having a different character letter thereon which corresponds to a note depicted on one of the control cards. The cubes are housed in a container and withdrawn one at a time by a player. In order to gain access to an instruction card to enable movement of his game piece, a player must compare the character letter on the cube with the notes depicted on the control cards and recognize the depicted note which corresponds to the character letter. Having done so the player is entitled to remove the underlying instruction card and move his game piece accordingly.
