A musical instrument’s keyboard consists of a row of depressible keys. The most commonly known example is a piano. Keys must allow an instrumentalist to play the twelve tones of the standard western scale with keys of two standard lengths repeated at octave-length intervals. When a piano key is pressed, it causes the instrument to produce a sound mechanically, in the case of an acoustic instrument, or electronically in an electric piano. Synthesizers have keyboards that look similar to piano keyboards. The origins of the arrangement of keys on a Korg Oasys keyboard dates back to the first century, but the evolution of the keyboard has been substantial. However, throughout its history, the basic layout of keys has remained fairly constant, resembling traditional instruments. Modern electronic keyboards can play some tunes, which have been pre-programmed, by themselves.
