Description
Some people consider the 432 hertz tuning softer and more relaxing or generally consider it more natural, harmonious and curative than the standard tuning at 440 hertz. However, the 432 tuning makes it impossible to play this model along with other instruments in the standard 440 hertz tuning as it is a dissonant combination.
Its operation is very similar to harmonium, but it has no keyboard. The top of the open bellows is hand-pumped. Inside the instrument, the air is pressed through metal reeds that vibrate for it. They produce the appropriate sound when the corresponding valve on the outside of the instrument has been opened.
13 one octave chromatic notes can be selected by opening the valves and thus making it possible to adjust to the singing voice.
