DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a tuner according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of an embodiment of a tuner according to the present invention. On the front of the main body case 1, the switch part 3
8 and display units 9 to 12 are arranged. Further, a voice input unit 2 for inputting a musical sound is provided on the side surface of the main body. FIG. 2 shows a tuning basic display portion 9 of the tuning device related to the display portion of the present invention.
FIG. FIG. 3 is a block diagram when tuning a Japanese musical instrument or the like using the present invention. 1 and 2, below.
An embodiment of the present invention will be described with reference to FIG.

The power switch 3 of the tuning device is pushed to turn on the power of the tuning device. The user can select the musical instrument to be tuned by pressing the mode musical instrument selection switch 4. The selected result is displayed on the selected musical instrument display section 9c of the tuning basic display section 9. By pressing the mode selection switch 5, the tuning method can be selected from the auto mode and the manual mode. The selected result is displayed on the mode display 9b.

First, as an example of selection, a case in which a koto is selected as a musical instrument to be tuned and an auto mode is selected as a tuning method will be described. The user selects the tone and the fundamental tone by pressing the tone selection switch 7 and the fundamental tone selection switch 8 in accordance with the tune to be tuned by the user. The selected result is the condition display section 1 respectively.
1, displayed on the fundamental tone display section 12. FIG. 5 shows a display example when flat tone is selected as the tone and Ikoshi is selected as the fundamental tone.

Under these conditions, when the non-tuning signal 13 is input, it is first converted into a pulse signal by the waveform shaping section 14. This time, from the signal converted at this time, the determination unit 15
The alphabet name, octave, and cent deviation are extracted and determined by.

Next, the control section 16 judges the information of the tone and fundamental tone inputted from the input section 19, and calls the data of the corresponding chord table from the storage section 17. FIG. 4 shows an example of the score table data stored in the storage unit 17, which is quoted at this time. In the case of this example, the data corresponding to the flat tone-Ichikoshi is called to the control unit 16. Then, the result of the alphabet name, octave, and cent deviation extracted by the determination unit 15 is compared with the called data, and the string having the closest data is selected.
Then, information on the name of the string, the name of the English note, the octave, and the cent deviation is sent to the display unit 19 and displayed. Specifically, the name of the string is displayed in the string name display section 10 and the English note name / octave is displayed in the English note name / octave display section 9d.

FIGS. 6 and 7 show display examples in which the string name, the English note name, etc. are displayed in this way. In the example of FIG. 6, the input signal is determined by the determination unit 15 to be the sound name A, octave 3, and cent deviation +15. When this result was compared with the flat tone-Ichietsu data by the control unit 16, it was found that the closest string name was three. For this reason, the display shows three string names, an English name A, an octave 3, and a cent deviation of +1.
The result of 5 is displayed.

Further, in the example of FIG. 7, the input signal is determined by the determination unit 15 to be the sound name D #, octave 4, and cent deviation -10. When this result was compared with the flat tone-Ichietsu data by the control unit 16, it was found that the closest string name was 6. Therefore, the display shows the result of six string names, English note name D #, and octave 4. However, since the string name 6 is a note name that is tuned with a tone name of 12 equal temperament -10 cents, as a result of adding 10 to the cent deviation obtained by the determination unit 15, the cent deviation is displayed on the cent deviation display 9a as 0 cent. It was supposed to be displayed as. That is, even if it is not conscious of shifting by -10 cents, if tuning is performed so that 0 cents are displayed on the cent deviation display 9a, a tune that is shifted by -10 cents is automatically tuned correctly. . Also, in order to show that this result is a string that is tuned to -10 cents, the cent shift note name display 9
e is also displayed.

Next, as another example of selection, a case where a koto is selected as a musical instrument to be tuned and a manual mode is selected as a tuning method will be described. When a tone and a fundamental tone are selected as in the auto mode, the control unit 16 calls the corresponding tone data from the storage unit 17 based on the designated tone and fundamental tone.
Then, the string name selection switch 6 is pressed to check which alphabet name, octave, and cent deviation the selected string name corresponds to, and the judgment result is displayed in the alphabet name / octave display portion 9d.

In this way, an example of display when the Douto string is selected when the tone and the fundamental tone are the Kumoi tone and the double tone, respectively, is shown in FIG.
Shown in. The control unit 16 calls the data corresponding to Kumoi tone-dual tone from the storage unit 17. Then, the alphabet name and octave to be shown by the selected string name are obtained from the table, respectively, and as a result, the alphabet name G # and octave 5 are displayed on the display unit 20. Furthermore, under these conditions, the Doutono string is -10.
Since it is known from the table that the string is a string that is tuned by cents, the cent shift note name display 9e is displayed again. The comparison result of the pitch name, octave, and tuned signal determined by this setting is displayed as a cent deviation. However, if the set string is a string that is tuned at -10 cents, the determined cent deviation is The result of adding 10 will be displayed.

By the way, when tuning a musical instrument such as a Japanese music by a tuning method based on the 12 equal temperament, the tuning is performed while comparing the strings on its own, but in the case of a tone to be shifted by -10 cents, the cent deviation It is difficult to know which position on the display 9a should be adjusted. Therefore, by displaying the cent shift index 9f at a position corresponding to −10 cents of the cent deviation display 9a as in the example of FIG. 9, it is possible to provide an easy-to-understand guide when tuning by shifting the cent.

[0016]

As described above, according to the present invention, a string corresponding to an input sound is displayed by selecting information such as a musical instrument to be tuned or a musical tone, and all strings are tuned when tuning is performed. Correct tuning can be easily performed by adjusting to 0 cent on the cent deviation display such as a meter. If you want to shift the cents to tune according to a tuning table that does not have preset settings,
By tuning the tuning mode based on the equal temperament according to the position of the specified mark, it became possible to simplify tuning of Japanese musical instruments such as the koto and shamisen.
