Abstract: A musical toy includes a train-like 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 extending down from the train may engage the note tiles to play the music so represented by the note tiles and track in the staff and note configuration.

Abstract: The electronic device uses domino-shaped sound elements in combination with a support track to generate audible sounds or musical notes. The sound elements are placed in indentations on a support track in a selected sequence corresponding to the sequence of musical notes in a song to be played. Each of the sound elements corresponds to a single sound or musical note. When the sound elements are toppled in a domino-type manner, the notes are played in the selected sequence. Each of the sound elements has one or more magnetic elements in its bottom surface. The movement of the magnetic element away from associated Hall Effect sensors in the support track during toppling of the sound elements is used to trigger a decoding circuit. The decoding circuit determines the note pattern and generates the associated sound through an output speaker. A timbre sound element may also be used to select the timbre or other tonal characteristics of the output sounds.
