There are 2 sets of reeds, voiced Bass/Male and a seven fold bellows. The 2 1/2 octave keyboard starts at the C below middle C and goes up to a high F. Thus it easily matches almost anyone's vocal range. It has 2 stops and 2 drones.

It folds up into a small suitcase sized box measuring 12 1/2 by 18 by 8 inches. Opened up it measures 12 1/2 by 18 by 11 inches. It weighs 18 pounds. The opening and closing mechanism is superior to and much more user friendly than the mechanism commonly used in Delhi style harmonums. The top detaches.
