The Harmonium is a small, manually-pumped musical instrument using fixed reeds to create the basic sounds. There are two main types of harmonium: a foot-pumped version that resembles a small organ, and a hand-pumped portable version that can fold up for easy transport. The hand-pumped portable version is very popular with Kirtan Jathas along with the Tabla and these form the main type of instruments used by Ragis during the performance of Kirtan.
