The harmonium is a wind instrument that looks like a small and portable piano or keyboard, but its sound is more like that of an accordion. It is a very popular instrument in India and other Himalayan countries.

The harmonium was brought to India in the 18th century by the French. Over time, the community of Indian artists developed their own original style of playing the instrument. Today it is used as an accompaniment for classical vocals, bhajans, folk and qawwali singers, tabla players, and Kathak dancers.

Almost any kind of song can be played on the harmonium. The basic bols of the harmonium are Sa Re Ga Ma Pa Dha Ni Sa and Sa Ni Dha Pa Ma Ga Re Sa. Songs are created by playing variations on the main theme. The sound of the harmonium is very mellow and pleasing to the ear.
