Abstract
An electronic tuning device has selectable width tuning ranges wherein selected pairs of the LEDs in a single row of LED's are activated, such as being turned on, blinked or flashed, so that the spacing between each activated pair of LEDs indicates the width of the tuning range during a range indicating mode. The sensing of a fundamental frequency of an input tone causes the operation of a corresponding LED in the row of LEDs to indicate the nearest note along with in-tune and out-of-tune conditions.
