Simple thumb piano, also known as a Kalimba or Karimba, made from wood a wood base and metal tines. The base is a hollow wooden box held together with metal nails; there are two sound holes, one near the center of the front and the other near the proper left edge on the back. There are 15 metal tines of varying lengths (although it appears there were originally more based on a gap near the middle), all bent into a curved shape; the tines are held in place by a piece of thick metal wire which is stretched across them and secured to the base through holes in the wood. To support the tines there is a stick wedged underneath them approximately 1.5 cm above the wire and a thin piece of metal wedged underneath them approximately 2 cm below the wire; each tine has a metal cuff located between the wire and the metal support piece.
