Clapboard piano (plywood piano): It means that the front panel, back panel and side panel are all made of plywood. Guitar plywood is generally made of three layers of bark glued together. The plywood piano has no timbre, and the wooden sounding part is replaced by glue, which makes the sound dull. It is convenient to make plywood pianos, without considering the drying of materials. The splicing method of plywood piano made in factory is generally to make the piano drum first, and then do it. This technique is simple, but it is easy to cause the neck of the piano to deform, so that the strings are high forward, or the head of the piano is tilted backward, resulting in a beat, but its price is cheap (the reference price is within 800 yuan). Personally, I think the full splint guitar can only be used as props or playthings. It is difficult to learn guitar with such a piano.
Single piano: It means that the middle panel of the guitar is made of logs, but the back panel is made of plywood. I think as a musical instrument, the single piano is the minimum grade requirement, and at least one panel is single board, so that the logs of the panel can play their greatest potential. When choosing a single piano, you should look at the material used in the neck. African peach core is generally preferred, and the material of fingerboard is also very important. Ebony is the best, followed by rosewood. Of course, for the finished piano, the best choice is to ask the guitar teacher to play it, try the feel and compare the timbre. According to the different materials of the splint on the back side of the piano, the layers of the panel and the materials of the fingerboard are also different. The market reference price is 65,438+0,000-3,000 yuan, and those that exceed this price should be those with particularly good appearance or domestic factories.
Single-board piano: The highest level of factory piano is also the most difficult to make, because the whole piano making process must be completed in a house with temperature and humidity control. Both the front panel and the rear panel are logs, and the process is complicated. After the side plate is bent, it takes a long time to set, so the cost is high, even if the number of pianos manufactured by the factory is limited. Such a piano can give full play to the original acoustic characteristics of wood. Among all guitars, the technology of all-board acoustic guitar is one. The price of imported single-board piano factory should be above 6000- 10000 yuan.
Handmade piano: It doesn't mean it is handmade. Factory piano is made by many people in a factory according to the specified drawings. Handmade piano is mainly done by one person, which is the difference in value between printed matter and works of art. It takes about 20 pieces a year to make a single-handed piano. Handmade piano has no brand, but is replaced by the signature of the pianist. In Spain, there is a manual luthier for every 10,000 people, and they are all family-style. When making a piano, the internal structure is determined according to the different characteristics of each material and the direction of wood grain, and the feel of the neck is made according to the requirements of the orderer. They will ask the subscribers what kind of timbre they need and so on. This is personalized production. In this environment in Spain, making pianos has become a part of their lives. They don't make pianos to get rich, as long as they can meet the basic living expenses. Therefore, Spanish piano makers can concentrate on making guitars and carefully carve the interior of guitars. Small internal changes will affect the timbre of the piano. In foreign countries, the price of hand-made pianos is about more than 3000 dollars, and the hand-made pianos will have the signature of the piano maker.

Summary: Factory piano is to shorten the production time of guitar and reduce the cost. Although some factories use better materials, they adopt simple methods in technology, the most obvious method is to connect the handles. Factory pianos are usually connected by dovetail inserts or wooden nails, so that the drums can be made separately and the trimming lines are easier to stick, but the sound transmission is not as good as that of Spanish piano-making method. The production method of Spanish handmade guitar is the most scientific and acoustic. In this method, the neck of the guitar is directly inserted into the drum, and the materials used to make the handmade guitar are all logs, which can be planed by hand tools, so that the characteristics of the logs can be preserved to the maximum extent. However, no matter how to make a guitar, as long as the player plays it, you must make more comparisons and shop around when buying a guitar. Only through comparison can you choose the guitar that suits you. Another reason for buying handmade pianos is the value of the collection. Handmade piano is unique, and there are many humanized things, which are not as dull as those made by machines. Many friends who play guitar think that playing handmade piano is much better than playing factory piano. After all, playing guitar is also an artistic expression. Choosing a good guitar does not mean that the tenor of this piano is better. The overall feeling is very important and cannot be measured as a kind of data.
Materials for making handmade guitars
An important criterion for most guitar lovers to buy a guitar is whether the guitar is a "single board". It is true that an excellent guitar generally needs excellent materials, but a guitar with excellent materials is not necessarily an excellent guitar.
The panel material of guitar is generally spruce (white pine) or cedar (Korean pine). It should be pointed out that not all spruce or cedar can be used to make guitar panels. Speaking of Korean pine, Ramirez III took the lead in using a kind of wood called "Western Red Cedar" on the panel. He realized that the supply of picea abies, which people like to use for a long time, was already problematic, so he began to look for other alternative materials. He pointed out that he used not ordinary cedar, but a North American pine named Thuya Plicata. The available trunk can grow to 20 meters high, and each tree can provide a lot of wood. If this special Thuya Plicata is not used as a panel, then the so-called "single board" has little substantive significance. I remember a friend said humorously, if the whole veneer is really so convincing, then his drawers are single and should have a good sound.
The European white pine we are talking about comes from several very old trees, and only the short part near the bottom can be used. This kind of tree is usually called "German spruce", but it is not only produced in Germany, but also in former Czechoslovakia (Bohemia). Recently, due to the continuous fighting in this area, the wood supply is extremely unstable. Similarly, it is of little significance to use other kinds of spruce casually. There are also some spruces that have proved to be good guitar making materials, such as some Japanese spruces (Hokkaido spruces) or American Englemann and Sittka spruces.
Ramirez's pioneering work has been imitated by many producers, such as Smallman, Byars, Hamphery, Kneipp, and some traditionalists, such as Fleta. However, the western red cedar is still controversial, so some producers are still reluctant to use it. Romanilos, for example, told Colin Cooper at 199 1 that the sound of western red cedar lacks delicacy, which is what a good guitar pursues. However, it is undeniable that more and more guitarists and guitarists use cedar boards. Moreover, through the continuous improvement of production technology, the "exquisiteness" mentioned by Romanji Roth has also been fully displayed on the Cedar Board Guitar.
Even if the wood we are talking about is used, there is still a problem of wood grade. As for how to judge the grade of wood, it needs very experienced experience. The more beautiful the panel material, the higher the grade. Some unattractive panel materials may have excellent sound characteristics, but producers generally choose materials from the perspective of sound. The characteristics of each material are not completely consistent, which requires the producer to make it according to the different characteristics of each board, which is also the difference between the producer and the craftsman. Artisans make it according to the size, and producers (artists) make it according to the characteristics of wood. Of course, the results of these two production bases are completely different.
In addition to wood itself, the quality of wood has a great relationship with wood cutting. Wood is generally "tangent", that is, it is cut from the bark to the central part, making 90 degrees with the annual rings. The wood thus cut has excellent elasticity and strength.
Rosewood is generally used for the back panel of classical guitars. Rosewood is hard and not as easy to crack as ebony, so it has good sound reflection performance. At the same time, this kind of wood has a very noble and beautiful wood grain, which is the first-class material for making handmade guitars.
There are many kinds of rosewood, including Brazilian rosewood, Indian rosewood and Honduran rosewood, but each rosewood can be divided into many kinds. The Brazilian rosewood (Dalbergia odorifera) that we usually talk about is also called jacaranda, and jacaranda is also classified. Brazilian rosewood is hard and looks more beautiful than other kinds of rosewood. However, due to fragility, processing is relatively difficult. Indian rosewood can also have a beautiful appearance, but its hardness is not as good as Brazilian rosewood. There are many famous guitarists in the world who tend to make guitars with Indian rosewood, including Romanilos, Fleita, Robert Rucker and byers. So it is hard to say that the guitar made of Indian rosewood is worse than that made of Brazilian rosewood. Dutch guitar master Vowinkel uses Brazilian rosewood and Indian rosewood to make guitars. Once I asked him the difference between the two. He thinks there is almost no difference between the two, but Brazilian rosewood is indeed more beautiful and the bass will be stronger, but there is little difference. Both kinds of rosewood are filled with refreshing fragrance, and Brazilian rosewood is more pleasant. Brazilian rosewood has long been hacked. Since 1992, the Brazilian government has completely banned the felling of Brazilian rosewood, and the United Nations has also listed Brazilian rosewood as one of the top ten endangered species in the world (the giant panda is the first and the Brazilian rosewood is the tenth). So it is difficult to obtain high-quality Brazilian rosewood now. At present, it is necessary to obtain a license to operate Brazilian rosewood, and there will be many troubles in import and export. If there is no license, it will often be considered as smuggling Brazilian rosewood.
Guitar fingerboards are generally ebony, and some low-grade guitars may like to use Indian rosewood or other worse substitutes. Ebony need not be painted. It should be black. Some ebony trees have white or yellow spots, which is normal.
Mahogny, as a guitar neck, was once a common tree species. In recent years, it has also been listed as an endangered tree species because of deforestation. In the future, more and more tree species will be included in the endangered list. So deforestation is a crime, and it is also a crime to use these rare trees to make inferior guitars.
In the future, producers will certainly develop more substitutes, but before mature substitutes are developed, the above-mentioned wood is the most ideal production material. Everyone has this knowledge, which is very good for choosing guitar in the future.
Finally, it needs to be emphasized again that materials are very important, but the most important thing is production. Without excellent production, it is meaningless to talk about materials.
