<!-- Harmoniums consist of banks of brass reeds (metal tongues which vibrate when air flows over them), a pumping apparatus, stops for drones (some models feature a stop which causes a form of vibrato), and a keyboard.
The harmonium's [[timbre]], despite its similarity to the accordion's, is actually produced in a critically different way. Instead of the bellows causing a direct flow of air over the reeds, an external feeder bellows inflates an internal reservoir bellows inside the harmonium from which air escapes to vibrate the reeds. This design is similar to bagpipes as it allows the harmonium to create a continuously sustained sound. (Some better-class harmoniums of the 19th and early 20th centuries incorporated an “expression stop” which bypassed the reservoir, allowing a skilled player to regulate the strength of the air-flow directly from the pedal-operated bellows and so to achieve a certain amount of direct control over dynamics).
