Is every tree musical? Each, but to varying degrees.

Experts consider spruce to be the most musical - resonant - species. But not every spruce can be suitable.

“Singing spruce” is a special species, it does not grow anywhere, it is most often found on the northern slopes, where there is less sun and the soil is poorer, and its trunk is well protected from the winds. Spruce should not be resinous, otherwise there will be no elasticity and sound conductivity decreases. It is important that the wood of the trunk is clean and straight-grained, and that it is at least a hundred years old.

Vologda spruce trees are distinguished by their great musicality. Their fame has long crossed the borders of our homeland.

The second most musical species is considered to be maple. Its best varieties - sycamore maple, or white, streamy - grows in the Caucasus and the Carpathians. Uniformity, elasticity, and long-term aging are important for this wood.

The best varieties of plane tree (plane tree) grow in Transcarpathia. Its wood is straight-grained, elastic and flexible, and is well processed and finished. Pipes, pipes, shepherd's trumpets and some plucked string instruments made from plane trees are distinguished by their special timbre and melodious sound.

Resonance beech grows in some areas of Russia and the Caucasus, on rocky, mountainous soils, at an altitude of 800 meters. His age must be at least 120 years. The wood is reddish in color, with parallel straight grains and a slightly glossy surface.

Ebony comes to us from Africa and India. It can be completely black or black-brown, uniform, well processed, and often used for decorative purposes.

Some musical instruments require more than a dozen different types of wood to create. For example, a xylophone has three or four rows of chromatically tuned wooden blocks lying on straw strands or thick gut strings. Musical blocks are made from maple, beech, spruce, rosewood, ash, chestnut and some other species.

Selecting a “singing” tree is not an easy task. A person of this unique profession, based on signs known only to him, must identify “musical” from a thousand trunks.

Bracker walking along snowy forest with a wooden hammer on a long handle, taps each trunk, putting his ear to it. Slowly, he listens carefully, as if in the very heart of the forest beauty only a melody that he understands sounds. It is relatively easier to work with fallen timber. Here there is a fresh cut in front of the scraper, and the secrets of musicality are determined with the help of a magnifying glass. The broker casts a spell over each tree for a long time before he puts a special mark.

It happens that resonant wood is harvested from dead trees, as was done in the old days. Having selected a suitable tree, it is ringed in winter, that is, the bark is removed from the bottom along the entire circumference. In spring, new shoots and leaves appear on it, drawing out all the juices from the trunk. A shriveled tree, deprived of sap, is cut down.

The selected ridges are sent to the factory, where they are sawn into boards, dried, and then turned into resonance boards in a special way. From these, parts of a musical instrument are subsequently glued together - soundboards, keyboard cut-outs for a piano, more musical blocks of a xylophone.

Before the revolution, foreigners who had their own musical enterprises in Russia used wood that came to them from the Carpathians, Vosges, Tyrolean, Bavarian mountains, Swiss Alps and mountainous regions of Italy. It never occurred to them to use “perishable” wood from the forests of Russia, somewhere in the Kostroma or Vologda province. Foreign material was purchased for a lot of money.

At Soviet power, by the end of the second five-year plan, the search for domestic wood began; and they turned out to be successful. Speaking about this, one cannot help but recall Marshal M.N. Tukhachevsky. He loved music, in his free time he made a violin and played this instrument superbly. Among his friends, he said: “There is nothing more beautiful than music... this is my second passion after military affairs.”

Head master violin instruments G. A. Morozov recalled how he once told Tukhachevsky that the workshops he led at the Bolshoi Theater lacked resonant spruce and maple. The reserves made before the revolution are coming to an end.

M. N. Tukhachevsky promised to help and kept his word. A special expedition was sent to Transcaucasia to search for the necessary wood species. Soon to Bolshoi Theater The USSR received a gift from the Marshal - two carriages of wood. In one of them there were “singing” spruce trees, and in the other there was a seasoned sycamore, several girths long. Once in the hands of leading craftsmen, the precious material turned into wonderful musical instruments, which have received wide recognition.

The mighty trunk of the spruce bends, as if thinking, then falls. Forestry manager Jiri Soukup is worried. It is always painful for a real forester to destroy a forest beauty. Moreover, the spruce is resonant: you can’t guess in advance whether it was cut down in time and what it is like inside.

Lumberjack Bogumil Maresh over thirty years of work in the forestry, he has knocked down more than one such giant saws off a thin circle of wood for analysis. Only after this will it become clear: the noble tree will sound in the hands of musicians or will be used for building materials. On the cut, experts noted especially valuable, clear, thin resonant layers those that had formed over the last half century, during the ripening period, when the tree was evenly overgrown with “muscles”. However, the most important thing for resonant spruce cannot be determined by eye: the specific gravity of the wood and its elasticity. This time the material turned out to be dense and elastic: instruments made from it will have a gentle, silvery voice.

Forests occupy a third of the area of ​​Czechoslovakia, mostly coniferous. Spruce is often planted at felling sites; it grows faster than other species. But the scientists at the tree nursery in Kamenica na Lipa are not only interested in early ripening. Here they study resonant spruce trees and grow material for musical instruments. In fact, from each smooth and dense trunk you can make soundboards for violins, cellos, or resonance shields for pianos. But it is no coincidence that violin makers carefully select trees for their future creations that can respond to the lightest touch. From time immemorial it was believed that the only place in Czechoslovakia where suitable spruce trees grow was the slopes of the Šumava River. But it turned out that a “musical” forest can also be grown on the Bohemian-Moravian Highlands, but for this you need to take special care of the trees.

There are half a million seedlings in the Kamenice nursery alone. experimental site. All Christmas trees are taken from local forests, because for normal growth there is no better soil than native soil. And when they grow up and get stronger, they are moved to permanent place residence, at an altitude of seven hundred meters above sea level. But Christmas trees, like all children, grow differently. Once every ten years, the plantings are thinned out so that the remaining trees stretch straight towards the sun, without bending. After forty years, if the tree is healthy, if its trunk is straight and rounded evenly, branches begin to be cut off from it so that layers of wood grow without knot nests.

Previously, they cut branches manually, but now they have come up with an automatic saw with remote control, which climbs up the trunk itself. The forester can only fix it on the tree and then pick up the fallen spruce paws. The cut points will heal over time, and then dense, undamaged wood will ripen along the entire length of the trunk up to the crown. When the period of rapid growth has passed, the spruce will “grow fat” slowly and completely imperceptibly by tenths of a millimeter per year. And the closer the annual rings are located to each other, the more valuable and uniform the wood will be.

The spruce must live one hundred and forty and one hundred and fifty years, only then it will be possible to make tools from it for which the master will not have to blush. Unusual for modern life pace! But so far no one has been able to make nature work faster. Therefore no human life not enough to grow a small Christmas tree to a fully grown, resonant age. And forester Jiri Soukup knows that he will not see the seedlings that he recently moved into the forest together with the pioneers from the neighboring Kamenice school growing. But he is sure that his forest will always have loyal and inquisitive friends like these kids. Many of them, after graduating from school, work in forestry. Others are still studying, but some of them will become a forester. And he will also teach children from a neighboring school. Generation after generation and the spruce planted by your great-great-grandfather grew. And each of the guys hopes that it will be resonant.

Even at first glance, this forest differs from an ordinary coniferous forest. Almost all trees are the same age. Slender gigantic spruce trees branches remained only at the very top make the forest transparent. The smell of fresh resin and the light rustle of the crowns can be heard freely. It seems that if the wind blows a little stronger, the trees will sound like organ pipes, and the forest will be filled with a solemn melody. Music of the future.

Wood, which is used in the production of soundboards for musical instruments, is called resonant, which means French sounds like resonance, and in Latin – resono and translates as “I sound in response.” This is due to its acoustic responsiveness over a wide frequency range, which gives musical sound a special timbre that is characteristic of this material.

Problems in choosing wood such as resonant
Not just any wood is suitable for making musical instruments. Even within the same species, both ordinary trees and those with resonant wood can be found.

In addition, to date there are no technical means and methods that allow for objective express diagnostics of wood directly on the root as a potential resonant raw material. There is also a lack of qualified specialists and investments in the industry that produces musical instruments.

Factors influencing such properties of wood as acoustic
Whether a tree has resonance properties or not is determined by genetic predisposition. Acoustic properties are influenced by indicators such as:
wood type;
growing conditions;
internal structure;
physical characteristics.

The quality of such wood also depends on such technological factors as the place and time of harvesting, drying and storage conditions, and transportation conditions.

Choosing a wood species
The best material, which is used in the manufacture of soundboards, is considered to be birch and spruce wood, as well as maple, pine, Siberian cedar and Caucasian fir. The best acoustic properties are characteristic of spruce, which has the widest application. This type of wood, when compared to cedar, improves its sound after drying.

Taking into account growing conditions
Resonance trees usually grow in mature stands, more than 150 years old. They prefer northern mountain slopes and rocky, poor soils. However, it has now been established that similar material can be found in forests growing on the plain and on soils with excess moisture.

Diagnostics of resonant wood: indirect methods
In the indirect diagnostic method, the following indicators are used:
appearance and condition of the tree;
bark color and structure;
macrostructure;
microstructure.

Peculiarities appearance
Resonant spruce has a vertical trunk with a cylindrical shaped area, devoid of knots and noticeable damage. The length of this zone is 5-6 meters. The crown of the tree should be pointed, narrow and symmetrical. First of all, these requirements are determined by economic considerations, when it is important to obtain maximum product yield.

Bark color and structure
There are different opinions about the color of the bark. Some craftsmen choose wood that is lighter in color or almost white, while others use yellow wood.

Regarding the structure of the bark, there is also no resonant spruce consensus. According to scientists V.O. Alexandrova and S.N. Bagaev, who were engaged in the selection of resonant spruce by phenotype, it is better to choose forms with smooth bark. Another domestic researcher N.A. Sankin believes that scale-barked spruce trees are preferable because they have the greatest genetic plasticity. Romanian craftsmen note that the bark should consist of rounded and concave scales. In France, it is believed that the scales should be small and smooth.

Macrostructure
The main criterion for selecting resonant wood, which is included in the standards of different countries, is the growth rings, characteristic features which are:
width;
equal layering;
the presence of late wood in their composition.

Wood with wide layers gives a muffled sound to the musical instrument, while narrow layers give it a harsh sound. As for the width of the growth rings, the optimal parameter will be considered a limit from 1 to 4 mm. Late wood in the composition of annual rings should make up 30%.

Certain types of resonant spruce wood are distinguished depending on the macrostructure on the radial section.
Flowy, which is characterized by straight annual layers with a slight wave-like shift of wood fibers. Such wood is elastic and produces pure tones. It is of greatest value in the manufacture of decks.

Fiery, which has a beautiful pattern and its structure is similar to tongues of flame.
Red layer, which is characterized by the red color of the late zone of the annual ring. It has the highest density, but its value is less than that of the first two varieties.

Microstructure
When considering the anatomical structure of such wood, the importance of the interpermeability of cell systems that are located across and along the axis of the trunk is taken into account, these are the medullary rays and tracheids, respectively. An important indicator is the presence of a large number of permeable pores shaped like a colon. This is especially true for early tracheids. It is for them sound waves spread throughout the entire thickness of the board, passing in the transverse and longitudinal directions.

Other indicators
High-quality resonant wood can be identified by its shine. Spruce, growing in the north of Russia, which has a silky and delicate shine, as well as with well-developed thin layers, gives the sound a silvery and tenderness. German craftsmen prefer wood with large and sharp sparkles.

In some situations, the smell of wood is used as a diagnostic indicator, by which its resin content is determined. It has been established that resinous substances have a negative effect on such properties of wood as acoustic properties.

Diagnostics of resonant wood: direct methods
For these purposes, the following wood indicators are measured:
density;
elastic modulus;
sound speed;
amplitude of oscillations;
the amount of energy lost due to internal friction.

The obtained measurement results are used to calculate the acoustic properties of wood. The next step is to determine the suitability of raw materials for the production of musical instruments.

Traditionally, musical instruments are made from materials with high quality resonating properties, aged in natural environment for many years to maintain acoustic qualities and stable structure. Resonant wood is harvested exclusively in the cold season. Spruce and fir are unique in their musical properties.

To create the soundboard, almost every musical instrument uses spruce or fir. Specialists carefully select so-called resonant wood. The tree trunk should not have any flaws and have equally wide growth rings. The wood dries naturally for ten years or more. In the manufacture of musical instruments, the resonant properties of wood are of exceptional importance. In this case, the trunk of spruce, Caucasian fir and Siberian cedar is more suitable than others, since their radiation power is the greatest. For this reason, these types of wood are included in GOST.

One of necessary requirements When creating musical instruments is the choice of wood. For many centuries, resonant spruce species have been of greatest interest to craftsmen. It was difficult to acquire raw materials of the required quality, so the craftsmen had to independently prepare wood for the manufacture of tools.

The places where spruce grows with the desired properties have become known quite a long time ago. Chief violin maker Russian direction XX century E.F. Vitachek, marked in his works the territories where spruce grew. In Saxon and Bohemian species spruce a large number of resins, it cannot be used in the manufacture of instruments of the highest class... Spruce from Italy and Tyrol was considered the best raw material... Luten manufacturers ordered Tyrolean wood from the city of Fussen, which is between Bavaria and Tyrol, and the Italian species from the port of Fiume on the Adriatic.

There are practically no forests growing in the mountains near Fiume in Italy. Therefore, we can assume that the spruce was not from Italy, but from Croatia or Bosnia. There was also an additional territory from which spruce was brought for craftsmen from Italy - these were the Black Sea port cities - spruce from Russia, the Caucasus and the Carpathians. As Vitacek wrote, since N. Amati worked, spruce, which is heavier, denser and rougher, is often used on the outer soundboards of instruments, while maple, on the contrary, has a low density. This is a very good combination: the sound becomes similar to the sound of a human voice. Italian masters This combination of maple and spruce wood has always been used.

However, spruce can have such properties only if it grows at the required level relative to the sea surface, that is, in the Alps or the Caucasus. A variety of the breed "Picea orientalis" growing in the highlands of the Caucasus and Asia Minor at an altitude of one to two and a half kilometers, its qualities are similar to the best views spruce of the European highlands. As a rule, it grows next to Nordmann or Caucasian fir (Abies nord-manniana), which also has excellent acoustic characteristics. Famous Russian violin manufacturers of the early twentieth century in most cases took spruce from the Caucasus to create instruments.

Wood species used in the manufacture of musical instruments

While creating plucked instruments At low cost, it is possible to use waste from woodworking factories, beams and boards of houses intended for demolition, parts of furniture and waste packaging. But these materials require special drying and selection. When creating high-quality instruments, it is necessary to use uncommon tree species.

Spruce

Instrument soundboards and other parts are made of spruce with resonant properties. Different subspecies of spruce grow almost everywhere in Russia. Spruce is used as a resonance tree, mainly in the central part of Russia. Spruce trees from the north of Russia are more popular and have better physical and mechanical properties. One of the best advantages is the presence of small growth rings, which make the tree elastic and suitable as a resonant tree.

Resonant trees are selected from the bulk of prepared lumber in forestry warehouses. These logs go to sawmills, where they are cut into 16mm boards. For the purpose of purchasing more Wood logs are sawed in six steps.

Wood for musical instruments should be free of knots, pockets of resin, curls and other defects. This is a strict quality requirement. Spruce wood has White color and a faint yellow tint, and when exposed to open air becomes quite yellow over time. Layer-by-layer planing and scraping of spruce occurs without problems with a clean and glossy cut. Sanding gives the wood surface a velvety feel and a slight matte shine.

Fir

In addition to spruce, to obtain resonant wood, you can take fir, which grows in the Caucasus. It does not have many differences from spruce, both externally and when checking physical and mechanical parameters.

Birch

Birch forests make up two thirds of the total number of forests in Russia. industrial production warty birch and downy birch are used. Birch wood is white in color, sometimes has a yellowish or reddish tint, and is easy to process. During tinting, the dye is absorbed evenly, and the tone is even. If birch wood is dried evenly and kept for a sufficient amount of time, it can be used in the production of such parts of musical instruments as necks and rivets. In addition, birch is used to make plywood, which is used for the production of guitar bodies. The instruments are finished with clean or painted birch veneer.

Beech

Beech is often used in the manufacture of musical instruments. Parts of necks, stands and bodies of gusli and other plucked parts in the music industry are made from beech wood. Beech grows in the southeastern part of Russia. The color of beech wood is pinkish with a speckled pattern. The good resonant properties of beech make it suitable for making instruments. Beech wood is processed and sanded by hand. When painted, stripes remain on the surface, which are visible when finishing with clear varnish.

Hornbeam

To imitate ebony, stained hornbeam is used in the production of necks and bodies. Hornbeam wood also has a hard and durable structure. Hornbeam grows on the Crimean Peninsula and in the Caucasus Mountains. Hornbeam wood is white with a gray tint. The wood planes well, but is difficult to polish.

Maple

Maple is just as in demand when creating expensive musical instruments as resonant spruce. Housings string instruments Maple wood gives a good sound. Sycamore and Norway maple species are the most widely used. These species grow on the Crimean Peninsula, in the foothills of the Caucasus, and in Ukraine. Maple wood bends well, and its wood pulp has significant density and viscosity. The texture is dark stripes on a pink-gray background. When applying varnish to sycamore maple, a beautiful pearlescent surface is obtained. If the coloring is done correctly, this property maple is intensifying.

Red tree

This name is given to several types of wood with different shades of red. This is mainly the name given to mahogany, which grows in Central America. This type of wood is also used for the production of fingerboards, as it has good mechanical properties. If you cut the trunk crosswise and make a transparent finish, it will look very beautiful, although it will be inconvenient to process.

Rosewood

These are several breeds that grow in South America. Rosewood wood lends itself well to cutting and polishing, but in this case Pore ​​filling and polishing are necessary. During processing, a special sweetish smell appears. Rosewood has very hard and durable fibers, purple to chocolate in color, and is used to make stringed instruments.

Ebony

A type of ebony tree that grows in South India. The best necks and bodies are made from ebony wood. The highest mechanical qualities of wood provide tools with the necessary strength and hardness. With a greater weight of the neck when using ebony wood, the center of gravity of the instrument shifts towards the neck, this is very much appreciated by professional performers. The shell of ebony wood, when properly polished, allows you to avoid overtones if the pick jumps off the string. Ebony fingerboards are abrasion resistant and hold the frets well.

Most often, resonance wood is used to make musical instruments - namely, their soundboards. The main musical instrument that has been made from this type of wood for centuries is the violin. Most suitable materials to obtain resonant wood - pine, spruce, Siberian cedar, Caucasian fir and maple. If wood has excellent acoustic properties, it can be used even if it has defects.

Today, resonant wood species are a unique natural raw material that is very expensive.

Russian musical instrument manufacturers began searching for resonant wood in Russian forests at the beginning of the 20th century. As a result of the research, it was found that domestic raw materials are in no way inferior to foreign trees in their acoustic characteristics and quality. The best physical and mechanical properties were shown by spruce from the northern regions, which has small annual layers, which provide it with a high modulus of resonant elasticity.

Signs of Good Resonant Wood

The highest quality resonant wood is formed in harsh (for example, mountainous) climates, as well as in dense plantings. According to the statements of masters who make musical instruments, a good resonant spruce should be completely vertical, have a narrow, symmetrical and pointed crown, a 5-6-meter area without knots and a trunk with a cylindrical surface.

Some French craftsmen believe that the bark of the resonant spruce should be gray and consist of smooth small scales.

In addition, the number external signs resonant spruce includes the absence of resin pockets, knots and other defects. Typically, resonant wood is white with a slight yellowish tint, which intensifies over time. outdoors. It should also be well planed and scraped layer by layer, and its cut will be glossy and clean. Sanded resonant wood has a velvety surface with a slight matte sheen.

There are only three varieties of it: flowing, fiery and red-layered resonant wood. Flowy is expressed by a slightly wave-like shift of wood fibers, fiery has a beautiful patterned appearance and looks like tongues of fire, and red-layered is distinguished by its red color.
