How to set up a guitar using a computer. Methods and programs for tuning a guitar

The correct guitar structure, as is known, absolutely in all cases predetermines the qualitative sounding of the performed composition. A lot of methods can be used for this. At the same time, with the development of modern computer technologies, it is worth paying attention to the solution of the question of how to set up a guitar using a computer, a tuner, a mobile gadget such as a smartphone or tablet, or "by ear" using a tuning fork.

General concepts of the guitar structure

In this section, the correct tuning of 6-and 12-string guitars will be considered . For those who do not know, it is especially worth noting the fact that the main notes in both cases are practically the same. The difference in the system is only that in the case of a 12-string instrument , 6 pairs of strings are used. In this case, the first (upper) three pairs of notes are built in unison, and the remaining four pairs (lower) - using an octave, when one of the strings in the pair sounds exactly one octave lower, compared to the basic tone.

Actually, both types of tools can be configured in several ways. Perhaps, it is here, and you can find a universal solution, how to adjust the guitar using a computer, although this method is not particularly widespread. For example, it is good for home use.

At concerts, professional guitarists often use the tuning of the instrument with a special device called a tuner, or "by ear". Naturally, the first method is more convenient, since all this can be done in silence. In this case, you can even notice the deviations in the structure of the guitar for tenths of a percent. You yourself understand that such a dissonance human hearing, as a rule, can not perceive. The maximum that can be expected is an audible deviation of a quarter of a tone. Here it is useful understanding how to tune the guitar with a tuner. But more about this later.

As for tuning the guitar "by ear", this technique implies the moment that a person should have, if not absolute perception, a very delicate ear that can perceive deviations in the sound of strings in unison (if tuning in the fret) or purity of sound Intervals between two neighboring strings. To do this, you really need to have a well-developed hearing that can catch not only the difference in sound, but all the dissonant vibrations and vibration that are created if two strings sound even with minimal difference.

As already clear, for this it is necessary to develop and improve their abilities. In the case of using the definition of musical intervals, triads and chords that sound when two or more strings are tweaked at the same time, a good knowledge of the solfeggio will not interfere. It is believed that in music education it is one of the most basic, not counting the ability to play the instrument itself.

All this methodology is suitable for tuning the guitar with the help of computer systems and special software products. This, so to speak, the basics.

How to set up a 6-string guitar

Now you can go directly to the setting. How to set up a 6-string guitar? The basic sequence from the first to the sixth string includes the second octave, the si of the first octave, the salt of the first octave, the first octave, the small octave, and the small octave. Notice, in comparison with the piano notation, here the system is increased by one octave. For example, the second octave on the guitar corresponds to the notes of the first octave on the piano.

Now about tuning "by ear" in frets. First we squeeze the second string into V fret. The sound must be in unison with the first open string (i.e., the same). This sequence of actions is performed for all other pairs of strings except for the pair of the second and third, where the system is performed using the fourth mode.

How to set up a 12-string guitar

Setting up a 12-string guitar on the main strings using the frets is exactly the same. But, as already mentioned above, the four lower pairs have a difference in octave. On the frets, you can use the same rules, but not the main strings, but additional strings.

On the other hand, solving the problem of how to tweak a 12-string guitar, you can use natural flaylettes (as well as for a 6-string instrument), but for a beginning musician this method is quite complicated.

Using the tuner to adjust the guitar

Tuning the guitar with a tuner in this situation is very simple. For acoustic instruments, in most cases, overhead or microphone tuners are used, which react to the oscillation of the string.

For electric guitars, you can use special tuners with line inputs or the same virtual ones.

Only in this case the instrument is included in the connector of the tuner itself or the PC sound card. By the way, here and useful understanding of the question of how to adjust the guitar using a computer.

Computer programs for guitar tuning

With regard to the use of software such a plan, in most of these applications are virtual tuners or guitar processors that have in their arsenal of tools for customization. In principle, the solution to the problem of how to tune a guitar with a computer, from tuning using a tuner cardinally is no different.

For the right settings, you can use the simplest applications like Guitar Tuner, in which, after extracting the sound (when selecting a specific string in the field to the right), the percentage of deviation expressed in decibels appears on the screen. After that, we simply adjust each string to full compliance with the original frequency, and then press the Play button. Here, the tone of each tuned string will be played.

Among applications of this type, you can find quite a few free software products designed for different operating systems, computers or mobile gadgets.

In Strum Acoustic GS or in the popular Guitar Rig application the algorithm is the same. It is necessary to select a tuner bookmark for tuning, and then compare the sound of the strings with the original frequency laid in the program itself. For example, for the first octave it has a frequency of 440 Hz.

In this case, the first program is an emulator of an acoustic guitar, and the second is a full-fledged guitar processor. When the deviation arrow shows the value of zero (either in graphical execution, or in percentage, or in decibels), you can congratulate yourself - the adjustment is made in the most correct way. This should be done for each of the six or twelve strings, taking into account the specific nature of the instrument itself.

In any case, both applications can work with both acoustics and electricians. Again, they can be designed for acoustic analysis of the incoming signal from the microphone or directly when the guitar is plugged into the sound card slot or into the headphone jack on the mobile gadget using a special adapter. As you can see, the question of how to tune a guitar with a computer is something particularly difficult.
