Types Of Keyboard. There are two major types of computer keyboards: Basic and Extended. The Basic keyboard contains 104 keys and is enough to perform all the functions that can be done on a Windows PC. The Extended keyboard may have additional keys and the design varies among the companies manufacturing them.
Most keyboard instruments of the baroque Era as well as early pianoforte had fewer keys than the current 88-standard (some modern piano like the Bosendorfer Imperial have 97 keys, 9 additional keys in the bass), and much of Bach keyboard works for instance can be played on such a restricted keyboard.
