Deca is what? Device, functions and description

When choosing or repairing a guitar, it is important to pay attention to its details. Deca is one of the most important and large parts of its body. And it is available on all stringed musical instruments. It depends on the sound and appearance of the guitar, violin, double bass, cello or other string. Experienced masters can make a guitar by themselves, choosing the right tree for the deck. We'll figure out what the guitar deck is, and find out where else this word applies.

For what the body of a guitar answers

Let us turn to physical laws. It is they who obey the sound of the guitar. According to them, the deck is an amplifier of the sound of the vibration of strings. It works simply: you touch the string, and it starts to oscillate. Its movements are transmitted to the tool body and come back through the resonator aperture, amplified several times.

When choosing a guitar, you must pay attention to the connection of the body parts and the quality of the decks and shells. The guitar body consists of the upper and lower decks, which are connected to each other by a shell. The shape of the decks and the resonator hole depends on the type of guitar. It can be:

• Ukulele (Hawaiian four-stringed instrument, this was played by Marilyn Monroe in the film "In Jazz Only Girls");
• Classical acoustic guitar ;
• dreadnought;
• Jumbo;
• Flattop;
• Good (stress on the first syllable);
• Gipsy jazz;
• Electroacoustic (may not have a resonator hole).

The shape of the guitar is responsible for the features of its sound and application. Also, guitars of different shapes can have different resonator holes.

From what tree do decks

For high-quality musical instruments do not choose plywood. It is good only for amateur low-cost models. Below we will consider the differences in the sound of plywood and the array, but for now let's return to choosing the right wood.

Depending on the location of the deck in the instrument, you can take for them a different tree. Most often used:

• spruce;
• Rosewood;
• Red tree;
• cedar;
• maple.

Some manufacturers can use more exotic types of wood to create the instrument, but in most models these grades are used.

Lower deck

It is a solid detail, with no additional elements. It is complicated by the fact that the wood for that part must have a different thickness. Sometimes in the middle and lower parts the difference of values reaches only a few tenths of a millimeter. The best deck (the lower part) is made of mahogany. However, some manufacturers in recent years have begun to use carbon fiber or other types of wood for this part. An unusual option is an Indian rosy tea tree.

Note that the shell, which helps to connect the top and bottom decks, should be made of the same material as the back of the case. The shell helps to make the body volumetric and sets its shape. It allows you to get a strong and high-quality sound.

Upper deck

The upper part of the string musical instrument case has a more complex device. After all, it contains devices for installing strings, a resonator hole and other important elements. If the technology of the top deck is broken, then the instrument can be discarded - you will not get a good sound from it.

The upper deck is the main detail of the guitar. It is she who receives the most attention in production. The best thing is to make it out of spruce. It is this tree that sounds best. It is with the help of spruce that you can make a quality instrument that is distinguished by a clear and sonorous sound.

Resonator hole

This is one of the most important details, located on the upper deck. It is also often called a voice, a detail that gives the instrument a voice. The most common option - a round hole in the body. However, the photos of the deck allow us to see that the round voice is not the only possible option. You can find tools that have:

• F-shaped slits;
• Several small round holes of different diameters, located on the side of the strings;
• Unusual for the device hole guitar Good (it is best to see in the photo);
• Oval with a gypsy tool;
• A small oval (located under the strings) in jazz;
• Non-standard and unusual branded options.

A resonant hole is necessary to absorb sound and transmit it after amplification inside the housing. It can not be cut at will, anywhere, it is important to correctly calculate the position of the voice, based on the shape of the guitar and the type of tree from which it is made.

Types of sockets

One and the most minor details of the instrument are its socket. This is a lining that gives the guitar an aesthetic and unusual look. Wizards perform it:

• Made of wood;
• Mother-of-pearl;
• Paper.

On cheap tools, the socket is glued on, and on the more expensive ones it crashes. Finishing work on finishing the top deck creating a varnish coating. Often masters put their rosette on their rosette or specific patterns.

A drop

This element of the top deck came to us from classical stringed instruments, which are played with a bow. There it has a slightly different shape and is located under the chin of the musician. If we consider the guitar (it is the most popular string instrument, so we are talking about it), then it has a drop at the player's fingertips. It is an overlay that is glued to the top deck. Its colors can be very diverse, lovers use a drop as an additional way of self-expression.

It is necessary, not only to ensure a pleasant appearance of the instrument. It was originally placed on the case, so that the deck does not lose its appearance when playing with a mediator. It is not forbidden to use a drop on classical instruments, as with the right choice it does not significantly change the appearance of the guitar.

Stand and nails

In addition to several aesthetic elements, the upper deck is equipped with an important functional part - a stand for strings. It is located on the top of the body of any stringed instrument: violin, cello, double bass, balalaika, domra and others. It is important to make this element correctly. After all, the strings on it must be held during the game with the help of special buttons.

Often called a pedestal pegs, holding the strings at a distance from the body and neck. Both of these elements are located on the deck, but they are responsible for different functions. It is interesting that firms producing musical instruments rarely play with the appearance of the deck (except when it is necessary to give another form due to the features of the model), but the form of the stand can be called the manufacturer without words. A striking example of this - the company Dean, which produces stands for strings in the form of a curved triangle.

Differences between the sound of a guitar and a deck of plywood and an array

The term "deck" we most often hear in connection with the guitar. One of the most popular topics on the forums is to find the difference in the sound of the body made of plywood and solid wood. The hardest way is to find the differences between the sound of an amateur. While a professional, even without seeing the instrument, can determine whether the case is made of noble material:

• Deck of plywood gives a surface sound (it is often described as cheap);
• Wood makes it possible to get a deep beautiful sound.

It is important to know that it is possible to accurately determine the sound characteristics only in a room with good acoustics. Of all the string instruments, it is easiest for an amateur to understand the differences in sound when the violin is tested. Even people who can not play will be able to appreciate the merits of the deck of a good violin from mahogany.

Where else is the name "Deca" used

The term "deck" is used not only in music (although in this industry it is more popular and known). This word you can find in many professional fields:

1. Skateboarders borrowed the term "deck" from musicians. So they call the main part of the board. This term is used by athletes riding on a longboard.
2. Mathematicians and physicists use the word "deca" as a prefix. It means an increase of ten-fold and comes from the geometric figure of the decahedron.
3. Melomaniacs use the slang term "deca" as the name from the tape recorder. In this case, the origin of the word English is from the tape deck.
4. The military decks are called the upper part of the bottom tanks. Seamen have the same root name "Dec", used to refer to the deck of military sailing ships.

This word is known to many as a proper name. For example, for fans of beer "Deca" - this is one of the Russian companies that produce this foamy drink. It is well known to people living in Novgorod. In addition, it is this company that produces 32% of all bottled kvass in Russia. She owns the following brands:

• Nicola.
• "Nikitich".
• "Big".
• "Stepan Timofeevich."
• "Russian gift".

At builders on hearing system "Deca". This water supply equipment is one of the German brands, which is distinguished by its high quality. It is made of vinyl. Now the company has opened several own production facilities in Russia and manufactures not only gutters from vinyl, but has a wide variety of siding of different colors and flexible tiles.

Owners of private houses that have a water supply system, sooner or later think about installing a modern septic tank. One of the most common models is Deca-5. Its capacity is enough to work in a house with a permanent residence. Domestic producer DEKA has developed this option, taking into account the volley discharge of water to 344 liters, that is, you can simultaneously include dishwasher and washing machine, wash and use other plumbing. The system will withstand even serious loads.

"Deck Tracker" - what is it?

Another meaning of the terms "Dec" or "Deca" was spread with the help of computer games enthusiasts. In Hearthstone, the deck is a slang designation of cards or decks. It was from this game world that the term "Dec Tracker" was adopted. This is the name of a program that can track the cards that have left the game and remain in the deck.

The legality of the use of such programs is still in question. On the one hand, the Hearthstone developers claim that this third-party application can be used (it does not affect the game, but only does what the player can independently fix with a pen and paper). However, the latest news indicates a change in attitude of game owners to "Dec Trackers". Now their use can lead to the blocking of the game account.
