    • A musical toy includes a wheel with a cylindrical face comprised of a magnetic sheet layer, a printed graphic and a top perforated layer such that when combined they form a radial array of rows of receiving recesses each preceded by a sequence indicator such as a number. These recesses are positioned to receive metal note balls by means of an upper housing containing lettered slots that correspond to the lettered columns of the musical analog in the songbook. The tubes of the upper housing are kept in alignment with the receiving recesses by a ratchet system that allows for controlled sequential advancement of the wheel. When the note balls are placed at predetermined locations corresponding with the locations of notes on the represented staff, they fall down a tube and are guided and into the corresponding lettered recess for that position on the wheel face. The note balls are retained by the magnetic attraction provided by the magnet sheet in the wheel assembly. When a motor is engaged to rotate the wheel assembly, switch operators extending down from upper housing contact the note balls to play the music so represented by their location in the staff and note configuration. A magnetic wand is provided for quick, convenient removal of the note balls to reset the toy for another song assembly.
