What is a Harmonium?
The harmonium is a keyboard instrument similar to an organ. It produces sound by blowing air through reeds using bellows operated by hand. Originally developed in Europe in the 19th century, the harmonium became extremely popular in India and is now an essential instrument in Indian classical music, devotional music (bhajans and kirtans), and Bollywood film music.
