The bars of the instrument are struck by mallets of varying hardnesses. The vibraphone looks similar to a xylophone and a marimba. The difference is that the bars of both the xylophone and marimba are made of wood. In general terms, the xylophone is a soprano or high register marimba (the difference being in the tuning and timbre). The bars of a vibraphone are made of metal. The vibraphone also has a sustain pedal like a piano that when depressed allows the notes to ring until the pedal is lifted again. The vibraphone originally got its name because it has a motor that turns metal discs, called pulsators, located under the bars at the openings of the resonators or tubes. The rotation of the pulsators gives a "vibrato" (more accurately tremolo) sound to the instrument. Without this motor the vibraphone could just as easily be called a metalophone because of it's metal bars.
