DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tuning apparatus for measuring a deviation between a fundamental frequency of a sound of a musical instrument or a tone signal and a reference frequency as a reference for comparison, and displaying the deviation.

[0002]

2. Description of the Related Art Generally, guitars and basses belonging to stringed instruments are used.
For example, a dedicated tuning device such as a tune is known. There are also tuning devices for some stringed instruments, such as ukuleles and violas.
However, there is no tuning device dedicated to other types of musical instruments such as brass instruments and woodwind instruments, and tuning is performed by using a tuning device called a chromatic tuner that displays 12 different note names. How to do is known.

[0003]

Heretofore, in a tuning apparatus dedicated to guitars and basses belonging to stringed musical instruments, the instruments to be tuned are limited to guitars and basses only. In addition, similarly, a dedicated tuning device such as a ukulele or a viola has limited instruments to be tuned. If you have only such a tuning device, for example, if you want to tune a completely different type of instrument belonging to brass instruments, such as trumpets with different tones,
The chromatic tuner had to be purchased anew or prepared separately. When a chromatic tuner is used, a chromatic (full 8th pitch, i.e., an octave of 12
In particular, when a beginner tunes a musical instrument having a different key, the displayed note name should be raised in pitch, because it is displayed in any of the twelve tones (name divided into chromatic scales). There are times when I can't understand what to lower. When the pitch name (relative pitch name) that is the reference of the instrument to be tuned is different from the chromatic pitch name, it often takes time to make a wrong decision and spend time on tuning. And in a scene such as a brass band using many different instruments, one beginner sometimes tunes a plurality of different instruments, and frequently tunes the wrong pitch. I have. A similar tendency can be observed not only for the brass band but also for beginners who individually own a plurality of musical instruments. It is an object of the present invention to display a relative note name along with a plurality of types of musical instrument names corresponding to chromatic note names as minimum information for a plurality of types of musical instruments in a tuning apparatus, so that even a beginner can make a mistake in tuning. It is to make sure there is nothing. Another object is to select a musical instrument to be tuned from outside from all kinds of musical instruments without being limited to a stringed musical instrument, and to provide a tuning device dedicated to the selected musical instrument.

[0004]

There is a musical instrument information storing means for storing information unique to musical instruments for a plurality of types of musical instruments, and a control means for extracting musical instrument information from the musical instrument information storing means. Thus, for a plurality of types of musical instruments, relative note names are displayed as the minimum information among the information unique to the musical instruments. This is characterized in that tuning can be performed quickly and reliably by providing tuning information of a musical instrument to be tuned to all musical instruments. In addition, from outside via input means,
By selecting the instrument you want to tune, only the tuning information specific to the selected instrument is displayed, making it easy to perform accurate tuning, especially for beginners of all instruments. . Further, according to the present invention, if a user owns a plurality of musical instruments, one tuning device can be replaced with a tuning device dedicated to each musical instrument. There is no need to own a tuning device.
