Harpika carved from a piece of Beech wood, It is basically a kalimba with strings and also a miniature/more portable lyre harp. The high hardness and density of the wood is enough to keep the tone and prevent the strings from acting on the wood. The sound of the instrument is warm and the tone is pleasant.
Metal string harp : The harp is equipped with durable steel strings. The bell is ringing and can fill the room. The shorter the string, the higher the pitch you get. The same is true for string tension.
