User:Yash Jain and john ciena/VARIETIES OF HARMONIUM

1. Standard harmonium is the basic form of the harmonium as depicted in the picture. 2. Portable harmonium is a standard harmonium that settles into a cavity and closes to form a suitcase shape. 3. Scale changer is also a simple harmonium with the difference that the keys are not fixed over the reed board. The keys are instead mounted on a movable plate which slides sideways making one key place able on another note. 4. Hand and foot harmoniums have bellows at foot level with the main body at a higher level and connected to the bellows with pipes.
