Abstract: The invention is directed to a vocal note indicating device for indicating the note of a vocal pitch signal. The device includes an amplifying means for amplifying an inputted vocal pitch signal and a square wave generator means. The square wave generator means is responsive to the vocal pitch signal from the amplifying means, and provides a square wave output signal substantially having a same period as the vocal pitch signal. A timer means is utilized for determining the period of the square wave and provides an output indicating a period of the square wave output signal. The device uses a microprocessor having a look-up table associated therewith to compare the output from the timer means with the look-up table to provide an output indicating the note and degree of at least one of sharpness and flatness of the inputted vocal pitch signal. A display means includes a plurality of columns of LEDs for displaying the note of the vocal pitch signal.
