Percussion instruments are those whose sound is created by being struck or scraped by a beater, hand or another similar instrument – drums, cymbals, rattles – with a few exceptions like whistles and the hammered dulcimer. Steelpans or steel drums are idiophones, not drums because the sound comes from the vibration of the instrument when it is struck, not from striking strings or membrane as on a drum. Originating in Trinidad and Tobago, traditionally they were made from oil drums/barrels.
The German word glockenspiel was used to describe the playing of small bells, “bell play”. Metal bars eventually replaced the bells and the instrument that was developed retained the name.
