Abstract
An electronic device for use in aiding the instruction of musical students. The device is comprised of a metronome and a plurality of tone generators, all under the control of a microprocessor computer. Input devices for the system take the form of a musical keyboard and a microphone. The metronome produces an audible regularly repeated sound in the loudspeaker of the device and causes a visual display of a plurality of indicator lights to be lit simultaneously. Pitch error information is displayed on a plurality of indicator lights which indicate musical sharp, flat or correct pitch. The tone generators produce tones in the loudspeaker under the control of the program in the microprocessor. The device has the capability of interacting with the student to exchange musical responses which each is capable of understanding and judging.
