The modern piano developed in the early 19 century. It uses the same chromatic keyboard layout as these earlier instruments, and it can have different characteristics, but a black-and-white chromatic layout is most common.
The classic acoustic piano keyboard has seven octaves of black and white keys, laid out chromatically. Whether the piano is an upright or a grand piano, the keyboard layout and size will almost always be the same. Older piano keyboards were traditionally made from ivory and/or ebony, but modern pianos are usually made with plastic key tops (a plastic coating over a wooden key), or an imitation ivory material called ivorene.
Ebony is a dense black wood. A hard, heavy, durable wood, it looks lustrous black. Ivory is a term for dentine, most of the time used as a material for art or manufacturing. It has availed itself to many ornamental and practical uses.
