Abstract:
An apparatus and method for instruction of a student which includes interactive guidance of the student through a series of lesson frames includes providing the student with a keyboard having a plurality of keys corresponding to the notes of a musical scale and generating a key relation signal in response to each depressed or released key. A video display has an audio tone generator associated therewith enabling the student to respond to the visually displayed images and audio tones by selecting one or more of the keys on the keyboard. The student is presented with a lesson frame representing an instructional activity requiring a response by the student on the keyboard. The student keyboard response is compared with a performance standard and an absolute performance evaluation result is generated. The absolute performance evaluation result is compared with an acceptable achievement level for the particular instructional activity and a next frame selection signal is generated. A next frame is selected for presentation to the student based upon the next frame selection signal.
A percussive action silent electronic keyboard provides electrical input signals for electronic music synthesis equipment. The keyboard includes a housing, and a keyboard array of a plurality of depressable pivoted playing keys adjacently arranged as a musical keyboard. Each key communicates with a pivoted silent hammer in a cam and follower arrangement. A stop is provided for stopping the momentum of each silent hammer which is caused to move about its pivot by following a camming surface of its corresponding key resulting from depressing of the key during playing action. An electrical switch provided for each key, and the switch is responsive to the playing action of the key for generating and supplying electrical signals indicative of the action to the electronic music synthesis equipment with which said keyboard may be used to generate music.
