摘要： An electronic tuning apparatus is constructed of an input device for inputting a tone signal to be measured, a signal generating circuit for generating a plurality of reference frequency signals, respectively, corresponding to a plurality of tone names independently for each tone name, a plurality of display devices, respectively, corresponding to a plurality of tone names and a plurality of display control devices, respectively, corresponding to a plurality of tone names. To the signal generating circuit, a scale selecting switch and a pitch adjustor are connected. Each display control device is constructed so as to display an agreement of the frequency of said tone name at a predetermined octave with the frequency of said input tone signal in the display device corresponding to said tone name. The display is realized by an on-off arrangement pattern composed of a plurality of turned-on luminous elements and a plurality of turned-off luminous elements. According to the electronic tuning apparatus of the present invention, it is not necessary to take a lot of time and labor for changing-over an octave and a tone name and, as the measurement results are displayed at once after a tone to be measured is inputted, a tuning for each tone name can be performed easily and quickly. Furthermore, a tuning, based on the equal temperament scale and the just intonation scale, is possible.
