Problems solved by technology

Therefore, there is a problem that a novice whose memory of each pitch to be tuned to is relatively vague needs to perform an operation of confirming each pitch to be tuned every time the pitching device is used.

Embodiment Construction

[0050] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. refer to figure 1 The appearance of the tuner 10 for erhu will be described. figure 1 (a) is a figure which shows the appearance of the tuner 10 for erhus, figure 1 (b) is an enlarged view of the appearance of the controller 12 as a part of the tuner 10 for erhu viewed from the arrow Ib.

[0051] The tuner 10 for erhu can be used even if the person who tunes the inner string G1 and the outer string G2 (the user of the erhu tuner) does not know the reference tones that should be tuned for the inner string G1 and the outer string G2. If it is high (unknown), by adjusting the tension of the inner string G1 and the outer string G2 so that the deviation displayed on the inner string tuning lamp 18 or the outer string tuning lamp 19 becomes smaller, the inner string can also be adjusted. The string G1 and the outer string G2 are easily adjusted to the reference pitch.

Abstract

The invention provides a chord regulating device which is characterized in that user can respectively set the first chord and the second chord as the reference pitch easily, even if he / she does not know the reference pitch of the first and the second chords which need to be regulated. Under the condition that the music pitch received by the microphone (31) is the pitch of musical alphabet stored in the boundary acoustic memory (36e), after turning off the exterior string tuning light (19), the interior string tuning light (18) displays the partial difference. When the interior string is regulated as the reference pitch, firstly the chord is regulated for leading the interior string b tuning light (18a) or the interior string # tuning light (18b) to twinkle, and then the interior string b tuning light (18a) and the interior string # tuning light (18b) are lightened. Therefore, user who uses the register (10) for urheen can easily set the interior string as the reference pitch, even if he / she does not know the reference pitch corresponding to the interior string.

Description

technical field [0001] The present invention relates to a string tuning device, and particularly relates to a device that can easily tune the first string and the second string respectively even if the person who does the tuning does not recognize the reference pitches of the first string and the second string that should be tuned. A tuning device set to a reference pitch. Background technique [0002] There are known tuning devices (tuners) for musical instruments that detect the pitch (frequency) of the string vibration of a stringed instrument such as a guitar, and perform tuning of the stringed instrument by displaying the deviation between the detected pitch and a reference pitch. For example, the tuning device described in JP-A-2004-53779 or JP-A-5-66767. The pitch tuning device described in this Japanese Unexamined Patent Publication No. 2004-53779 is a pitch tuning (string tuning) device for guitars, and the reference pitch is set according to each string of the gui...
