The frame’s wood is from a tree called a Neem tree, the same tree which is used extensively throughout Africa to make ‘Chew Sticks’ employed very effectively to clean teeth. The wood is much lighter in colour and weight compared to the mahogany keys. The struts are cut using a hand axe, then planed down to a smooth finish. The cross members are bound to the longitudinal pieces using wet goat leather, which contracts upon drying forming an extremely tight bind. The frames are immensely strong, easily able to carry the weight of a grown man.
