From Wikipedia, the free encyclopedia.
The harmonium is a small, manually-pumped reed organ.
There are two main types of harmonium: a foot-pumped version that resembles a small organ, and a hand-pumped portable version that folds up for easy transport.
The harmonium was invented in Europe in the early 19th century. During the middle of the century it was imported to India. While the hand-pumped harmonium is still used in many genres of Indian music, in western culture both types of harmonium have fallen out of wide use.
