One look at the Harmonium and you almost think of it as a miniature version of a piano. Despite the similarity, the sound quality is entirely different. The Harmonium is also known as the ‘pump organ’ or a reed organ that produces sounds that contain ‘bellows’.Harmonium is made up of different parts that give it a different sound:

  • Bellows: These are basically a series of metal tongues that permit the air to flow. The bellows need to be hand pumped to enable the air to flow and produce the sounds. The left and right ends of the bellow are affixed with a latch or a metal bar to help both left and right handed musicians.


  • Keyboard: This enables the musician to play melodies and is also known as the unique aspect of the harmonium. Each key produces a different and unique sound. Although the structure and format of the keys are like a piano, the keyboard is relatively smaller in the harmonium.


  • Main Stops: These are actually the big knobs on the side of the harmonium that direct air flow. In fact, these main stops impact the way the sound is produced. For instance, if the knobs or stops are not pulled out, then the harmonium will produce no sound at all.


  • Drone Stops: These stops help to produce the constant sound of a single note. This is one feature that not all harmoniums possess.


  • Coupler: This is another special feature in some harmoniums. If a key is played a similar key of a lower octave will be played simultaneously to produce a rich sound.


  • Scale Changer: Some harmoniums might have this feature which helps to change the positioning and pitch of the keys. Even though this is a nice feature, it often results in problems for the harmonium.
