Double Reed & Triple Reed
Most harmoniums have two or three sets of reeds per note. See below for how these reeds can be voiced. Double reed instruments can be great, and all you need. A triple reed instrument will give you a fuller sound and more flexibility.
Portable harmoniums fold up into a suitcase-like box ½ to 2/3 of their regular height. There is a handle in front so they can be carried with one hand like a suitcase. If you are traveling around a lot with your instrument this is an attractive option, since it’s lot easier to carry a harmonium this way than by the two side handles of a regular harmonium. If you’re not, then it’s just another moving part. In general, you sacrifice no sound by getting a portable.
