A musical toy includes a vehicle traveling on a track which includes visual indicia representative of a standard nine note musical staff. Note tiles having first fastener halves may engage with second fasteners at predetermined locations on the track corresponding with the locations of notes on the represented staff. Switch operators facing down from the train may sense the note tiles to play the music so represented by the note tiles and track arranged in the staff and note configuration. The note tiles and track fastener features could be constructed in a format similar to the familiar stud and tube blocks of the popular Lego® system. An additional row of fastener halves could reside on the track adjacent to the main musical staff or outside the rails to allow for placement of tiles that could trigger sharp or flat notes, standard chords or perhaps percussive beat patterns. Also a cap placed on the top of the note blocks could trigger a distinct signal that could change the output to produce sharps, flats, a shift to a higher or lower octave or similar effects.
