Answer:
Ebony is a very hard but brittle, black wood, which is often used for decorative purposes, but its hardness is also used, for example, in details for musical instruments. The black keys on the piano used to be often made of ebony, as details on modern string instruments still do. Ebony grows in tropical areas. The type of wood is also available in other colors such as white, green, red and variegated depending on where and in which continent it has grown.
