is a short-resonator reed stop on the pipe organ, so named because of its supposed resemblance to the human voice.
The vox humana is intended to evoke the impression of a singing choir or soloist, though the success of this intent depends as much upon the acoustics of the room in which the organ speaks as it does the voicing of the pipes.
The vox humana is one of the oldest reeds in organ building, based on its appearance in very early instruments.
Many American organs built in the romantic style include a vox humana in order to facilitate the playing of this literature.
Vox humana stops in very old organs had a fairly wide variety of designs and tonal qualities.
