Abstract: A toppling tone-producing toy apparatus for producing a plurality of tones comprising a plurality of tiles, each tile having a front face, a back face, and a peripheral edge; a plurality of striker bars, each striker bar coupled to the back face of a tile; a note mechanism coupled to each tile for producing a tone when struck by a striker bar on another tile; a support mechanism for holding the tiles thereon; and a plurality of hinges, each hinge coupling the peripheral edge of each tile to the support mechanism for allowing pivotal movement of the tile, the coupling of the tiles with the support mechanism creating a generally aligned configuration where the front faces of the tiles are directionally aligned and each tile is offset from adjacent tiles by a distance less than its height such that when a tile is toppled towards an adjacent tile, its striker bar contacts the note mechanism of the adjacent tile, whereby toppling the adjacent tile, producing a tone, and creating a toppling effect that ripples thro
