Harmoniums are bellows-driven, free-reed keyboard instruments related to
parlor reed organs. They have keyboards that are similar to piano accordions, only with shorter keys.
Unlike the reed organ, the harmonium is pressure-powered, not vacuum-powered.
Harmoniums are used extensively in South Asia for classical and meditative music.

Sruti Boxes are smaller bellows-driven, free-reed drone instruments.
Unlike harmoniums, they have no keyboard and play a drone accompaniment, not melody. Players can play several drones at once to play chords.

The Pankaj publication Learn to Play on Harmonium by Ram Avtar 'Vir' divides Indian harmoniums into these basic types:
- Simple harmonium: played with one hand while the other pushes a bellows at the back.
- Coupler harmonium: made with an octave coupler.
- Suitcase harmonium: folds into a suitcase shape, for portability.
- Scale change harmonium: contains a movable keyboard.
- Organ type harmonium: a foldable harmonium with foot pedals.
Classified by bellows type, Vir describes three types:
- Single bellows: accordion-style bellows attached to a plate at the back of the instrument.
- Double bellows: has an additional segment of bellows.
- English bellows: made by uniting several pieces of small bellows. The bellows remains connected with both the plates like a simple bellows, but opens from one side. This bellows has the highest capacity of force to blow air in.
There are 3 keyboard sizes available:
- 3 octaves, with 37 keys
- 3 1/4 octaves, with 39 keys
- 3 1/2 octaves, containing 42 keys
