Bayan: history, video, interesting facts, listen. What is the difference between button accordion and accordion: device, keyboard Bayan short description

The right mechanism of the button accordion Jupiter 64/106 in the process of assembly.

So, the price of the same button accordion, the photo of which flaunts on my profile picture, is 350,000 rubles. Do not look for Swarovski inlay on the case, it is not here. This is an ordinary serial button accordion. The fact is that the production of button accordions is a long, laborious, practically non-automated process.

The time of creation of this musical instrument is longer than the time of bearing a human cub. A long eleven months pass from the moment the work begins until the birth of the finished button accordion. Eight different masters are involved in this difficult process. 80% of all production is done by hand.

Left hand action of a ready-to-select accordion, an experimental version. The process of developing a new tool model. Designer - Lavrov Viktor Petrovich.

If you decide to start making harmonicas, you should not google technical schools and universities that produce the corresponding masters. The creators of these musical instruments will have to be taught from scratch. The process of training one professional takes at least 2-3 years.

For the birth of one button accordion you will need:

Master in Nodal Mechanics

Furrier

Case maker

Resonator maker

Left mechanics assembler

Right mechanics assembler

Tuner

There is not a single person who would combine all these specialties. It is very, very rare to come across a master who is excellent at two of these eight wisdoms, but no more.

The salary of a metropolitan harmonica maker is approximately 35,000 rubles. Taking into account the cost of renting a room, it is better to organize production somewhere in the provinces, and maybe outside of our vast country.

Production of resonators: installation and gluing of partitions.
Master - Kudar Mikhail Ivanovich

Perhaps the largest harmonica factory is located in Pyongyang. 1100 people work there, of which only 80 are managers, and the rest are workers. Mostly accordions are made there. This factory and the Moscow company "Jupiter" have close friendly and partner relations.

This is how a musical instrument is made. The instrument turns out to be very, very nice.

Final stage creation of harmonics - tuning.

The last step is setup

By the way, the accordion is the younger brother of the button accordion, and not vice versa, as many people think.

In general, the button accordion is by no means something irrelevant, as they like to say in the vastness of Runet, but a popular, interesting and very serious musical instrument. Here.

reed musical instrument

The sound of the accordion, button accordion, accordion happens due to humming metal reeds voice bars. When air passes through the slot of the bar, the metal tongue vibrates in the slot and a sound of a certain tone is heard. The air is blowing fur. Each plank has two tongues that make the same sound. The tongues are located on different sides.

For air to pass through unclenching fur through one tongue. And when squeezing fur through another. Opposite each of the two slots of the voice bars, a small strip of skin(not shown in the picture) One strip closes the slot of the voice bar when the fur is compressed. The other when unclenched.


For every sound of a certain pitch own voice box. In an accordion, button accordion, accordion, there are as many voice bars with sounds of various pitches as the instrument can play notes. Tool range - 3 to 7 octaves. That is, from about 20 to 80 sounds. For richness of sound, an octave is placed on each note two voice sticks. And the registers make it possible to sound several different voices on the same note.

Pressed the key - opened the air valve

How manage so many votes. Creating from these voices music. By pressing the desired keys playing the instrument opens the desired air valve. who guides air from fur to the right sound chamber. Air exits through the voice bar.

To install resonators, valve and other mechanisms near the instrument there are two decks. At the right side right deck. On the left side left deck. There are decks wooden or metal. Decks have sound holes. The holes of the resonators coincide with the holes of the decks. The sound holes of the decks close and open valves when you press keys tool. Decks are adjacent to the body sides hermetically. To all the air from furs went to make a sound

Ivan Kopytin's Blog Bayan Accordion Accordion

Well, let's start with the simplest. I will say, for starters, that the accordion ishand harmonica (primarily a reed keyboard-pneumatic musical instrument), invented and widely used in Europe.

In the Russian tradition, it is customary to call accordion instruments with a right-handed piano-type keyboard, but there are also button accordions with a keyboard like a button accordion. The very name was given


by the Viennese organ master C. Demian of the accordion improved by him in 1829.

Main components:

Frame. For the manufacture of the body, beech, maple, alder, birch wood was used and is most often used. But accordions with an oak body are extremely rare and are made only to order. But sheets of aluminum are necessary for the manufacture of the lattice. Outside, the body is pasted over with celluloid.

Vulture. The melody keys are placed on the neck, it is attached to the right half of the body. And it is made from the same material as the body.

Fur. For the manufacture of fur, cardboard is pasted over with a cloth, hermetically fastened to the right and left half-hulls. It consists of 13 or more folds, which, when squeezing and unclenching, create air circulation that makes the instrument "sing".

By the way, here's a hack: the fur folds should be glued with adhesive tape or electrical tape to avoid too rapid wear of the crev fur at the points of contact with the chest of the performer ...

Resonators. A necessary part of sound extraction are resonators with voice bars.

Voice bars. Voice strips are called metal plates with openings, above which the tongues are located. Each note has a separate reed. The shorter the reed, the higher the sound, respectively, the longer - the lower. The tongues are riveted to the plate with their thickened end, the free end of the tongue enters the slot of the plate and vibrates under the action of a passing air stream, forming a sound. Voice strips are made of non-ferrous metals, brass and aluminum. The quality of the sound depends on the precision of the reed attachment, the quality of the material, and the type of body wood.

register system. Made from aluminum and brass. Used to change tone.

Device.Two keyboards connected with furfor pumping air into the keyboard-pneumatic mechanism. Device air valves accordion:

Musical instrument mechanismallows you to control the air flow through the reeds , up to its complete cessation (green arrows in the diagram). Depending on the direction of the air flow, one of the two reeds of the same tone of the chamber fluctuates (blue and orange arrows in the diagram). In others musical instruments(For example, harmonica ) the reeds of one chamber may differ in musical tone - harmonist changing the direction of movement of the fur changes the pitch (musical note) without removing the finger from the key. The left (side, bass) keyboard of the accordion is arranged differently: pressing one button, thanks to a complex mechanism, opens several cameras at the same time ( chord ). The mechanism is common to accordions, button accordions and other similar musical instruments.

There are several varieties of accordions: normal and ready-elective .

In the usual bass (left hand) plays as expected according to the row scheme:

In the picture you see a diagram of a conventional left keyboard in a mirror image (B - major, M - minor, 7 - seventh chord, Um - diminished chord).

But in the ready-to-elective there is a switch from the above scheme to a completely different one. By means of a switch, the accordion switches to the mode of changing the entire left keyboard to only basses (notes). That is, where in the usual chords, in the selective keyboard - notes.

The left keyboard in the selection is the mirror right keyboard on the button accordion.

Accordions are also classified by size:
1. Full - 4/4 - 41 keys; range - from F small octave to la third octave.
2. 7/8 - 37 keys; range - from F small octave to F third octave).
3. 3/4 - 34 keys; range - from salt small octave to mi third octave.
4. Half - 1/2 - 26 keys; range - from si small octave to before third octave.

Everything seems to be ... Something like that. If you have any additional questions or something is not clear - do not hesitate - contact us.
Oh yes, there are also electronic accordions, but that's another story...
P.S. If you notice any errors in text, please let me know.

The left keyboard consists of five (and sometimes six) longitudinal rows. These rows are counted in the direction from the fur to the edge, that is, the row closest to the fur is called the first.
The keys of the longitudinal rows of the left keyboard are not located exactly opposite the keys of the first row, and each row is slightly shifted upwards, in relation to the previous one. Thus, transverse rows that are slightly beveled upwards are created.
The keys of the 1st and 2nd longitudinal rows, when pressed, give bass sounds. Each key of the 3rd, 4th and 5th rows (and in some instruments also the 6th row) gives the sound of finished chords.
The main row of the left keyboard is the second longitudinal row of basses, which is called the main row.
The keys of the main row are not arranged in the order of scale steps, but in such a way that each adjacent key, counting from bottom to top along the keyboard, gives a fifth sound higher than the previous one.
Approximately in the middle of this row there are seven bass keys, of which the first white one from the bottom gives the lowest sound of the button accordion - the note F of the contra-octave; the adjacent white key gives a sound up to a large octave, etc.



The basses of the second row are the main sounds in relation to the sounds of the chords of the remaining rows, that is
The black key next to the note F down gives the sound of B-flat, the second black key down gives the sound of E-flat, etc. Thus, the sounds extracted on the white keys of the 2nd row, as a whole, constitute the scale of the C major scale, but not in the usual order. The five black keys of this row, in relation to the white keys, produce chromatically modified sounds (i.e., flat and sharp).
Seven white and five black keys give all 12 chromatic sounds within one octave. In addition to seven white and five black keys, in the same row there are also white and black keys, which are a repetition of those mentioned above; they are for convenience (to avoid jumps).
The first row of the left keyboard is called auxiliary. The keys of the first row are located among themselves in exactly the same way as in the second row and are a repetition of the 2nd (main row), but the first row in relation to the second in height is shifted up by a major third (in writing notes).
Thus, against the sound fa of the 2nd longitudinal row (the first white key from the bottom) is the sound la.
The auxiliary row, which gives third sounds to the main bass row (2nd row), is of great convenience and makes bass playing much easier.
The auxiliary row keys in the notes are conventionally denoted by the letter B, which is placed under or above the note.
The basses of each key of the main and auxiliary rows are recorded with one note, although when the corresponding key is pressed, not one sound sounds, but three sounds of the same name in three octaves at once:

The third longitudinal row gives major triads (or their inversions), built from the main basses of those sounds that are extracted by the adjacent keys of the second longitudinal row. The fourth row gives the chords of the minor triads (or their inversions), and the fifth row gives the dominant seventh chords (or their inversions).
In the button accordions of some designs there is also a sixth longitudinal row, which gives the sounds of chords of diminished triads.
The basses of the second row are the main sounds in relation to the sounds of the chords of the remaining rows, that is, the chords depend on the name of the bass against which they stand in the transverse (oblique) row. In other words, each main bass along the transverse oblique row has three ready-made chords related to it.
When you press only one key of the 3rd, 4th, 5th and 6th longitudinal rows, a whole chord sounds at once, but all the sounds included in the chord are still written in the notes. The sound of these chords does not go beyond the small and first octaves.
To make it easier to find chords on the button accordion, the following symbols are used in the notes:
1) major chords (large triads) are denoted by the letter B;
2) minor chords (small triads) are denoted by the letter M;
3) dominant seventh chords are indicated by the number 7;
4) diminished triads are denoted by the letter U.
If after the bass there is a chord that has one of these conventions, then this chord is taken in accordance with the designation in the same transverse (oblique) row in which the bass is located.
To make it easier to find the desired key on the keyboard, a small note in brackets is written at the bottom of the chord, which indicates which main bass the chord should be taken from:

In example 2, the bass si is taken in the auxiliary row, and the next major chord from the note G is in the same transverse row as the si note.
If the chord is above the bass note, then the bass and chord are played at the same time, that is, two keys, bass and chord, are pressed together.
In these cases, a small note in brackets may also be signed under the chord, indicating which bass the chord should be played from:

If the bass is written with notes of long durations, and the chord has a shorter length, the notation in notes has the following form:

The most widely known button accordions are with a three-row keyboard in the right hand and with ready-made chords in the left, five- or six-row keyboard. Such button accordions, according to the place of their original manufacture and distribution, began to be called Moscow, in contrast to the so-called Leningrad, four-row ones. Now there are button accordions with five rows on the right keyboard.

In addition, there are elective button accordions with a three-row keyboard in both the right and left hands. Here the chords are freely selectable on the keyboard, just like on the piano, depending on how they are written. Recently, combined accordions have appeared, on which you can play both as an accordion with ready-made chords, and as an elective one.

Orchestras of folk instruments use orchestral button accordions with one right keyboard. Their whole family: piccolo, soprano, alto, tenor, bass and double bass. They differ from each other not only in range, but also in timbre. In addition, there are special orchestral - timbre button accordions: in sound they are similar to the flute, clarinet, bassoon and other instruments of the symphony orchestra.

Consider the device of a conventional three-row button accordion with ready-made chords.

The box-shaped wooden body of the button accordion consists of two halves, interconnected with fur. Inside each half-body there are decks, on which resonators with voice bars are fixed from the side of the fur, and on the outside - a valve mechanism with a keyboard.

The keys of the right hand are placed on a special bar - neck, and the left - on the front wall of the semi-body. Both mechanisms are covered with lattice covers from above. From the inside, the covers are pasted over with a thin thick cloth, which is a filter that protects voices from dust.

A short belt is fastened on the left half-body, under which the left hand is passed when playing. In addition to playing the keyboard, the left hand stretches and compresses the fur, pumping air.

Two straps are attached to the right half of the body, which are put on the shoulders and firmly hold the instrument during the game, freeing right hand from supportive efforts.

The fur is a four-sided corrugated box, pasted over with fabric on the outside. The fur is glued to small narrow wooden frames, and they are already directly attached to both halves of the body with hairpins or hooks. The places where the fur is bent - the corners - are glued from the inside with strips of husky, thin soft deer skin, and from above for greater strength they are strengthened with special metal corners.

The body of the button accordion is glued together from thin beech or birch planks. The corners of the body are glued into a spike " dovetail". In addition, the top corners are fixed with metal decorative plates that protect them from damage and sticking.

Unlike soundboards on other instruments, bayan soundboards are not a resonating device, but serve only as a mechanical airtight partition (diaphragm) between the fur chamber and the valve mechanism. They are made of good, even and durable plywood, birch or beech. Several rows of holes are drilled in the deck, which are blocked from the outside by valves and against which the holes of the resonant chambers are installed from the inside.

The sound on the button accordion arises as a result of vibrations of a thin steel plate (tongue, voice) over a slot through which a stream of air is driven. Slots are made in massive durable stainless steel strips, brass, aluminum and others. The slats are solid or split, consisting of small plates, separate for each sound, more precisely, for each pair of reeds.

Tongues or voices are made of special spring steel, they are firmly riveted to the slats above the voice slots. The dimensions of the slots, the length, width and thickness of the tongue depend on the pitch of the sound: they are the larger, the lower the sound, and vice versa. Small copper plates are soldered onto the reeds of the lowest bass tones to make them heavier.

Above the slot, from the side opposite the tongue, a strip of husky is glued, which closes the glottic fissure during the reverse movement of the air stream, and thereby reduces air consumption, fur consumption during the game.

Each pair of voices on the bar is against a small resonator chamber - gorodushka. The volume of the chamber, its shape and dimensions are important for the strength and timbre of the sound, so they are specially calculated and designed.

Gorodushki together with planks make up a separate structure, the so-called resonators. At the bottom of each gorodushka, wide holes are drilled for air passage, which coincide with the same holes in the deck. The resonators are glued together from birch or alder. Each row of keys on the neck corresponds to a separate resonator.

In all joints where there is a danger of air leakage: between the planks and walls of the towns, between the resonators and the soundboard, a seal is laid - strips of fleecy soft husky. The slats are attached to the resonators with curved studs or small studs with wide heads. In addition, the edges of the planks are filled with molten wax.

Valves are small wooden plates, on the underside of which strips of soft kid are glued, and a wire leash is fixed on top, with the help of which the valve rises and falls, blocking the holes in the deck. The fleecy side of the husky fits snugly against the soundboard, preventing arbitrary air from entering the voices, and softens the impact of the valve on the soundboard during playing. Sometimes, to reduce noise when playing, a strip of thin cloth is additionally laid between the valve tree and the husky.

Keys right keyboard are narrow wooden levers, which are placed in the appropriate sockets on the fingerboard and rotate on a wire axle. On the top side of the neck, mother-of-pearl or celluloid buttons - buttons are strengthened with a key, and holes are drilled at the other ends with a key, into which the ends of the valve leashes are screwed or glued. Below in the slots under the keys there are springs, under the action of which the valves are tightly pressed against the deck.

Thus, all three rows of valves are arranged on those button accordions where the neck is closer to back wall corps. In the same place, where the neck is located closer to the middle of the body, the third row of valves has a slightly different arrangement: the valve leads are bent in a special way and are attached to a wooden plank glued to the soundboard with the help of two loops. The end of the key is brought under the free curved end of the valve leash and presses on it, lifting the valve. In this case, the main valve springs are installed not: under the keys, but directly on the deck, near the axis of rotation of the leash. Under the key itself, in addition, there is an additional small spring that tightly presses the pushing end of the key to the end of the valve leash, eliminating the gap between them and the inevitable idling of the key in this case.

On the fretboard of a bayan of mass production, fifty-two keys are usually installed, the range is from large cu-flat to C-sharp of the fourth octave. On bayans made to order, the number of keys reaches fifty-eight, sixty-one, and even sixty-four. Range with fifty-eight keys: from large salt to mi of the fourth octave.

The arrangement of the mechanism of the left keyboard is much more complicated than the right one. The presence of a bass that has an octave tripling or even a quadrupling requires a special design of the voice plates and resonators. The push-button system of mechanics should provide wide selectivity of chords in the range of small and first octaves.

Let's consider the device of the left keyboard of the button accordion, which has one hundred and twenty bass buttons: six rows of twenty buttons in a row.

The left keyboard is associated with two rows of valves: one row (12) is for basses, and the other (also 12) is for chord voices.

Under the bass valves are four voice bars, mounted on separate resonators, but assembled into one unit. The build of each bar differs from the adjacent one by an octave. When the valve is lifted, four octave sounds sound simultaneously, for example, when the bass button is pressed, they sound simultaneously to large, to small, to the first and to the second octaves. This octave bass boost is necessary to create a certain strength and thickness of the sound. On some button accordions, the bass is only tripled: the bar for the highest voices is not set.

Each bar has twelve pairs of voices arranged in chromatic sequence. The range of all four bass bars is from E contra octave to E flat second octave. The bass valves are controlled by the first two (from the bellows) rows of the left keyboard.

The entire complex chord keyboard controls the sound of only one resonator, which has two continuous voice bars on it. There are twelve pairs of voices on each bar, they are located on both sides, as usual, and are tuned in a chromatic sequence from G minor to F-sharp of the first octave.

All bass and chord valves are connected with special bolsters, located along the valves parallel to the deck, with the help of stud leads. For each tone - a separate roller; thus, there are two sets of rollers - twelve bass and twelve chord.

Each roller has several studs that take the force from the pushers rigidly connected to the key with a button. The buttons through the corresponding holes are displayed on the front wall of the left half of the case.

When playing, the movement from the finger is transmitted through the pusher button, on which in a certain place - near the pin of the corresponding roller - there is a small pin. The pin touches a pin, rigidly fastened to the roller, and causes the roller to turn. Turning, the roller moves the other pin on it, which, with the help of a leash, is connected to the free end of the valve leash: the valve rises and opens the holes in the deck to let air pass to the vocalists.

The mechanics of the chord keyboard also work in a similar way, with the only difference being that there are several pins on the pusher that actuate several valves at the same time. So, for example, when you press the G minor triad button, the pusher with pins touches the pins of the rollers associated with the keys of the sounds G, B-flat and D, and opens them.

The button accordion's left keyboard has six vertical rows of twenty buttons each. The first two rows, counting from the fur, are basses, the remaining four are chords. In the first row are the so-called auxiliary basses - a large third from the main bass; in the second - the main basses, tonics; in the “third row - major, large triads; in the fourth, minor, small triads; in the fifth - dominant seventh chords with a missing fifth; in the sixth - diminished seventh chords

The middle of the left keyboard has seven rows of white buttons, these are the keys of "pure" tones, their main basses do not have sharps or flats. Below the white buttons are five rows of black buttons, the main basses of which are flat. Above the white keys there are also five rows of black buttons, the main basses of which have sharps. The corresponding rows of upper and lower black buttons, although they have different names, sound the same, they are enharmonic equal (for example, the key in C sharp is enharmonic equal to the key in D flat). In other words: the black buttons at the top and bottom duplicate each other. In addition, there is one row above the black buttons and two rows of white buttons below the black ones, which duplicate the three extreme rows of white buttons.

Such a large number of duplicating keys is necessary to make it convenient for the performer to play in any key without unnecessary jumps from the top of the keyboard to the bottom and. vice versa.
