Harmonium

 

 

The harmonium, also known as the pump organ, was widely used in smaller churches and in private homes in the 19th century. It is not regularly seen in classical music, for the obvious reason that larger and more capable organs are at hand in concert halls and churches. I am aware of only one concerto for it, by Dutch composer Martijn Padding. It is played by Dirk Luijmes with the Asko-Schoenberg Ensemble under Etienne Siebens on Etcetera.
