Celesta

Struck idiophone operated by a keyboard

The celesta or celeste, also called a bell-piano, is a struck idiophone operated by a keyboard. It looks similar to a four- or five-octave upright piano, albeit with smaller keys and a much smaller cabinet, or a large wooden music box (three-octave). The keys connect to hammers that strike a graduated set of metal (usually steel) plates or bars suspended over wooden resonators.
