1, some brands of guitars will play if the timbre is not standard!

2, adjust the height of the bridge, or consider changing the string pillow! Adjust the height of the neck string! Try to adjust the neck and bridge repeatedly, just find the best point, be careful!

3, you can adjust the neck of the piano and screw the hexagonal screw hole on that piano head! Twist it bit by bit and try it out bit by bit! If the string is clockwise, it will be loose, if it is counterclockwise, it will be tight. Pay attention to the moderate bending of the neck and bend in the direction of the fingerboard! But don't turn too much, the pitch will be destroyed!

4. It will be fine when you buy it. As soon as the place changes and the climate changes, products can be made! This is the principle that metal expands when heated and contracts when cooled! Never mind, just warm! Try not to adjust easily! Pay attention to the protection of the piano, don't let it get wet or something!

5, it is also related to the strength of playing! Hit hard, a little!

6, the products are uneven, if a product is high, you can use your own drama to break and scrape the product with a piece. It was hard to fight in one place, but it wasn't so hard after shaving! Do it gently!

7. Adjust the chord. The neck of the piano should be slightly concave, and the products at the back should not be bounced. When the bridge is tuned, the strings are higher. Products can be changed, and there are many models to choose from, but this is a technical job. Find an experienced one to change it for you!

8. The order of piano tuning is: playing copper, lifting the bridge, adjusting the fingerboard, and tossing the piano pillow! Low-grade piano, the performance is generally tilted on one side or both sides, and it can be improved by knocking on the bridge! Use a plastic hammer to shorten the high pin hammer!

9. After playing the sixth string of the piano, raise the bridge by the side of the sixth string, and the problem will be solved!

10, the thicker the strings, the softer and rounder the sound. The harder the material, the brighter the sound (such as carbon treble strings). The lower the tension, the more comfortable the string is, but it also increases the possibility of playing (of course, the problem of playing mainly depends on the guitar itself).

How to tune a box piano with excessively high strings.

A few days ago, my friends always had a headache about the feel of their pianos. They generally report that their strings are too high and it is very difficult to press them! On this issue, everyone also said their own methods, some said changing the strings, some said adjusting the neck and so on! Today I will summarize it in detail! May not be very comprehensive, I hope you can add!

1 Change the feel by adjusting the neck! First of all, look at the state of the fingerboard and strings. If the strings and fingerboard are sunken, the neck will be adjusted! The method is to insert the hexagon wrench into the hexagon nut at the sound hole (and some pianos are adjusted at the head), and then turn it to the right! This will change the state of the neck, thus changing the height of the strings!

If the neck of the piano is adjusted, but the piano feel still can't meet your requirements, then you need to grind your saddle (that is, the long thing on the bridge), take it down and polish it with fine sandpaper! It should be noted that the grinding must be uniform! You'd better try the piano while grinding! Otherwise, if you grind the saddle too low! There will be a phenomenon of hitting products! You have to buy a new saddle!

The adjustment of the piano pillow can be ground with a small poke, but it is very dangerous! If you grind the strings of the piano pillow unevenly, the feel and timbre of your piano will change greatly, so this method is not recommended. If you really want to use this method, you'd better ask the pianist for help! Because there are special tools to adjust the piano pillow!

4 is to change strings! The thickness of the strings will also affect the feel. If your strings are thick and affect the sense of the piano, you can change a set of thin strings! But from my personal experience! The effect of adjusting the piano feel in this way is not obvious!

Here is the standard of the height of the lower chord! In the case of different products, the chord distances of 1, 2, 3, 4, 5 and 6 are 1.8 mm, 2.0 mm, 2.2 mm, 2.6 mm and 2.8 mm respectively. You can decide according to your actual situation, but don't exceed this value too much!

Selection and maintenance of guitar

There is an old saying in our country: "If a worker wants to do a good job, he must sharpen his tools first." . When you get a satisfactory Jihua, you will not only put it down but also get twice the result with half the effort. On the other hand, if you get a finished product with poor quality, you will lose your enthusiasm for playing with it. When buying a guitar, the beauty of appearance should be put in the second place. First of all, we should pay attention to its "sound quality". Here are six aspects to tell you the knowledge of distinguishing the quality of guitar.

1, carefully check whether the neck and fingerboard are straight with eyes. If the fingerboard of the sound space sinks or the middle part of the neck is arched, it can't be used any more. This kind of defective product often looks intact, so you should be extra careful when buying it.

2. The distance between the strings and the first fret is generally 1.0/ 1.2mm, and the distance between the strings and the twelfth fret is 4.5/5/0 mm ... Higher than this figure, it is not only difficult to press the strings, but also leads to "out of tune". This kind of guitar can be used by an experienced guitar teacher after adjusting the chord distance.

3. The vertical and horizontal surfaces of copper products are made of flat, wide and round geometric shapes. The product leveled with a file is the back of the knife, which will not only damage the strings, but also hinder the fingers of the left hand from sliding on the strings and dampen the transposition speed. This kind of guitar is not suitable for use.

4. Tap on all parts of the singing body. If there is a muddy and hoarse sound, it means that there is cracking or glue opening in a certain part.

5. When tuning the string to the standard pitch, do you find that the shaft can't turn? Try to play it to see if there is any evil.

6. Play the scales and chords of each key, and listen to whether the pitch meets the requirements, whether the volume, timbre and pronunciation between strings are balanced, and whether the feel is appropriate.

Obviously, it is difficult for a beginner to check the above six aspects. Why don't you entrust an expert or your guitar teacher to buy a guitar for you?

When you have a guitar, you must take good care of it to prolong its service life. Please pay attention to the following three aspects:

1, the metal part of the chord shaft needs to be lubricated frequently, usually once every quarter. In the process of tuning the strings, always pay attention to the tension of the strings, and don't adjust them too high at once to avoid breaking them.

2. When the guitar is not used for a long time, you can relax the strings; If you want to play often, you don't have to relax the strings. Guitar should be played frequently, so that the air in the box can circulate and keep it dry. Generally, it should be hung in a ventilated place, not in direct sunlight. Excessive drying and humidity can cause the adhesive to crack.

When you take the guitar outdoors, you should put it in a cloth guitar box, which can be made according to the size of your guitar.

Guitar maintenance

1, delay the aging of strings: aging of strings is an inevitable measure (why not stainless steel? The neck is too hard? Because the strings will rust for various reasons, such as sweat stains on your hands and humidity of the surrounding environment, you should wipe them with a soft dry cloth or paper towel before and after playing the piano.

2. Maintenance of the piano body: If the right hand touches the piano body for a long time, a layer of dirt will accumulate on the piano body. In fact, it has a more severe impact on the body than the piano, but there are countless bacteria on it, so once found, it should be removed immediately.

3, low-grade guitars should buy a piano box, high-grade guitars should buy a piano box, which is convenient for guitar storage.

4. The sudden change of temperature and humidity will do harm to the guitar. Avoid direct sunlight on the guitar and stay away from the heating. If the air is too humid, you can put some desiccant in the piano box.

High-grade guitars are exquisite in craftsmanship and fine in material processing, so they are particularly vulnerable to injury. Never put the guitar on the table or floor. Pay attention to the scratches caused by your zipper and buttons.

6. Play regularly so that all parts of the guitar can fully vibrate at any time. This is the best way to maintain all the parts of the guitar.

Basic knowledge of strings

1. Good strings should have good sound quality, fast tuning, stable pitch, good playability (safe fingers and quick response of strings) and long life (if you play the piano for 2 hours every day, the strings should last for about 3 months).

2. Different brands or different models of strings of the same brand are usually the result of manufacturers trying to pursue higher possibilities in the above five aspects, or they try to have different performances in one aspect (such as bright or soft sounds). They achieve their goal by adjusting the composition materials of the strings (increasing or decreasing the silver content of bass strings or the carbon content of treble strings, etc.). ) and process flow. The manufacture of strings is not a precise science, and each brand of strings has its own unique characteristics, as well as good and unsatisfactory places. No manufacturer produces the best or perfect strings.

It's a good idea to listen to other people's opinions, but it should be noted that different people have different standards when evaluating strings. For example, an instrument maker generally prefers strings with few features (neither too bright nor too soft), so as to highlight the characteristics of the guitar itself. A performer often has his own specific voice choices (such as simple bass, bright treble, etc.). There is no absolute aesthetic standard for these preferences, which depends on the guitar itself and the player's style. Therefore, a set of well-behaved strings is not necessarily the best choice.

4. The tension of strings is a big aspect, and there are many things to say. Tension is necessary for strings. We rely on the adjustment of tension to make the strings reach different pitches. Generally speaking:

Tension is generally divided into five grades: ultra-low, low, medium, high and ultra-high. The tension level of strings depends on the standard length determined by the manufacturer (for example, daddario is 648mm. If the strings are installed on the guitar and the service length exceeds 648mm, then higher tension is needed; If it is less than 648mm, the required tension will be smaller. Therefore, when considering string tension, don't forget different standard lengths. The greater the tension, the thicker the strings. The thicker the strings, the softer and rounder the sound. The harder the material, the brighter the sound (such as carbon treble strings). The more nervous.

The lower the string pressure, the more comfortable it is, but it also increases the possibility of playing (of course, the problem of playing mainly depends on the guitar itself). Greater tension does not mean greater volume. Strings with higher tension will vibrate more violently, but this form of vibration does not play a major role in volume. Guitar itself, especially its internal structure, plays a much more important role in this respect. To give a typical example: a group of ultra-high tension strings, it is likely that too much pressure will be exerted on the panel, which will cause the panel to start to block the sound. When considering using ultra-high tension strings, be sure to ask your guitar manufacturer about your piano's ability to withstand string tension. Many producers won't advise you to use ultra-high tension strings on their guitars. Most players will feel comfortable with strings with medium tension, high tension or a mixture of medium and high tension. I don't recommend you to use strings with low tension or ultra-low tension, because its sound is finer than most players can imagine.

How to appreciate the quality of guitar

For the purpose of teaching and sales, it is convenient and feasible to consider the quality of guitar from five aspects: material, design, technology, feel and timbre. Only by investigating at least these five characteristics can we have a comprehensive and objective evaluation of guitar.

Because guitar lovers don't understand that guitar evaluation needs to be grasped from the integrity and comprehensiveness, it is easy to indulge in a small aspect of guitar and not see the whole picture. For example, some fans may hear that all good guitars have "dense and symmetrical" stripes, or that "the denser the stripes, the better the sound". Therefore, since then, fans have been paying full attention to these minor issues.

Materials: According to the materials used, guitars can be divided into various grades, which can be basically divided into: full-board guitars (such as many cheap Asian guitars, the price is 50 -400 US dollars); Guitar, the front panel is veneer and the back panel is plywood (price is 400-2000 USD); Full-board guitar (starting at 1000 USD or 1 100 USD).

According to the hardness, color, curvature and stripe density of wood, the cost of a solid wood panel is about 10-100. As far as the back and side panels are concerned, hardness is usually the most important factor affecting the price. Backboards and side panels of mezzanine are usually $ 8-30, $20 for solid mahogany, $ 50- 100 for Indian rosewood, $ 80- 150 for Spanish cedar, and $ 400-800 for Brazilian rosewood (Brazilian rosewood is very expensive because of the international embargo on such exports).

A high-end classical guitar agent recently revealed to me that the above information about wood prices may mislead some consumers because they can't see the potential cost. What needs to be clear is that consumers should realize that after wood is collected, it must be properly dried and aged-it may take many years.

Correct drying process will greatly increase the cost of basic wood. In addition, consumers must realize that even exciting wood may have hidden defects, so it may not be used.

Wood must be properly cut and dried. Most of the wood used to make guitars is dried by kilns (kilns are specially designed drying equipment that can control the humidity of wood during heating and drying). If the humidity of wood is too low during heating, it may crack. It takes about 1 month to dry a piece of medium-density wood, such as mahogany, with a thickness of 1 inch; It takes longer to dry wood with higher density, such as rosewood or ebony. Some masters who customize guitars like to air-dry wood because they claim that naturally dried wood will sound better. A piece of hardwood with a backboard may take several years to dry naturally. The wood used by felix manzanero, a producer in Madrid, has been naturally dried for more than 30 years.

The importance of wood drying (whether drying or air drying) cannot be underestimated. If the wood is not dried before making the guitar, the guitar will be unstable. When the wood finally dries, the result may be that the neck of the guitar is bent or the guitar body or panel is broken.

Different parts of the guitar need different personalities of wood. Experience has proved that European white pine, engelmann white pine and Korean pine, and California Korean pine are all suitable for making plates; Brazilian rosewood, maple and

Some redwoods are suitable for rear side panels. Spanish Korean pine or Cuban mahogany is suitable for the neck. Ebony or rosewood is suitable for fingerboard.

Twist differs greatly in price and quality. Simple nickel knobs cost about $ 5- 15 each; High quality brass or alloy is about $65438 +05-80. Hand-carved gold knobs (such as fustero knobs in Spain) cost $ 250-300 per set.

Design: Design involves aesthetic and practical issues, and aesthetics involves the proportion and shape of guitar. For example, the modern Spanish guitar, starting from 65,438+02, has a length ratio of 3: 4 at the top, 2: 3 at the waist and 65,438+0 at the bottom. The design of a beautiful guitar follows these hidden geometric principles; The outline of the piano body, the design of the piano head and the form of the hollow ring also follow the classic design principles, which have long been deeply rooted in Gregory-Roman aesthetics and the concept of proportion.

Technology: Technology includes woodworking and assembly technology. In recent years, the technological level of factory guitars has been greatly improved. Modern equipment can make the appearance of guitar perfect, comparable to the craftsmanship of the best masters.

The advantage of factory guitar production system over custom guitar system is that according to an excellent design scheme, high-quality guitars can be manufactured at a lower cost than custom guitars. take for example

The wood cutting machine can cut 1 0 necks with uniform standard and shape within 1 minute, but if it is cut by hand, it may take1hour for one neck. On the contrary, one of the advantages of custom guitar is that the luthier can modify the original design according to the characteristics of wood (such as the thickness of the panel or the installation of the sound beam), so that the sound potential of a specific wood can be fully exerted in theory.

For laymen, the technical level of guitar is sometimes difficult to identify, of course, defects such as wrong cutting, saw marks, lax seams and so on are easy to see; Other problems are difficult to identify, such as whether the combination of neck and body is V-shaped connection or oblique connection.

Modern guitars mostly use catalytic propylene paint, which is very durable and the coating is not too thick and will not affect the sound quality. In the guitar factory, the painting process takes 5 days. 25-50

A few years ago, guitars used nitrocellulose lacquer. Because this kind of paint needs a long drying time and polishing, the painting process takes several weeks. The most time-consuming paint is French paint (mostly insect paint), which takes 30 hours and takes 4-8 weeks to complete. The above-mentioned coatings have different appearances, each of which has a slight influence on the sound quality. Which is the "best" is a matter of opinion. Generally speaking, high-quality French paint is the most expensive.

Touch: Guitar hands feel the influence of many factors, such as the angle of the neck, whether the neck is bent, the shape and fluency of timbre, the height of the bridge, etc. .

Guitar with low chord distance is easy to play, but it is not conducive to the long-range and continuity of sound. Therefore, many well-trained and powerful players tend to raise the chord distance, and such guitars will be very uncomfortable for players who lack professional training. Playing in front of a large audience without amplification equipment requires a guitar with a high chord length; A piano with a low chord distance is more suitable for recording or adding wheat.

At Fernandez Music Festival, I personally adjusted the chord distance of each guitar to achieve good performance. This adjustment should at least move the piano code, so that the chord of classical guitar 6 at 12 is 4 meters, and the chord of 1 is 3-3.2 mm (the chord of rotten menge guitar 6 is 3.2-3, and the chord of 1 is 2.7-3.0). In addition, I also check the height of sound products, compare every three products, and then reinstall or polish them if necessary.

Sound: The quality of sound involves accessibility, balance, persistence, clarity and so on. The ability to distinguish the sound quality of a guitar takes several years of training. The most important way to test the sound of guitar is in the room.

Listen from one angle, not just behind the guitar. Is the sound transmitted well as a whole? Is the treble loud and clear? Is high school bass balanced?

Thin-panel guitars can easily play rich bass, and treble is a problem. Perfect sound requires the panel to be hard enough-neither too thin nor too thick.

Many people may hear the difference between "good guitar" and "poor guitar", but few people can feel the difference between "good guitar" and "excellent work". This ability to appreciate the guitar needs professional knowledge as the backing, and it takes years of training to get it. The five criteria for evaluating guitar introduced in this paper are just some basic requirements.

Finally, it should be pointed out that price is only the embodiment of market demand, not quality, and different people will be interested in different things. We know that the quality itself does not determine the price, because the guitar must have a signboard, and fame means money. An unknown guitar has a limited market; In addition, the price of an ordinary guitar may rise sharply because it is related to a celebrity.

It is very difficult to evaluate a guitar accurately because many evaluation criteria are contradictory. But in any case, in the long run, quality and price are closely related to the reputation and social recognition of manufacturers to some extent.
