The Wangare workshop’s largest jaw harp, along with the “Magicians” using reeds of the same length, is a catastrophic-sized design with an eye-catching design. The sound of the instruments is loud, sensitivity is high; the timbre is not the smoothest, but extraneous mechanical sounds are almost invisible.
