ABSTRACT:
A musical keyboard instrument comprising an electronic keyboard and a control panel. The keyboard is composed of black and white keys arranged in a conventional pattern. A keyboard display made up of LED displays and red-green illuminators inform a user of the proper finger and hand positions to be used on the keyboard. To view the keyboard display when it is activated, the user simply looks directly at the keys. Each red-green illuminator mounts on the interior of a housing such that a pair of red and green lights extend into the hollow interior of one of the keys. Normally, the keys appear to a player as conventional black and white keys. However, the upper surfaces of the keys are made partially transparent and light dispersive such that its apparent color to a player will change when properly back lit by the red-green illuminators. The illuminators and the LED displays are controlled when a user makes selections from a bank of pushbutton switches. The illuminators and LED displays may also be controlled by input signals provided by an external computer system.
