Introduction to accordion

Accordion Introduction

The accordion is a reed instrument capable of both solo and accompaniment. It can not only play the beautiful music of a single voice, but also the music of multiple voices, you can also play a wide range of harmony with your hands like a piano. The sound of the accordion is huge, the tone is rich, and the fingers and the wind box are cleverly combined to play a variety of different types of music. In addition to independent playing, you can also participate in the concert and ensemble. In addition, the fixed pitch, easy to learn and understand, small size, and easy to carry. Therefore, the accordion is suitable for players of different ages to entertain themselves, it can also be easily carried to schools and theaters for performances.

The accordion player must be played with both hands at the same time. When practicing the piano, the fingertip of the player keeps in touch with the keyboard and button at different speeds and times, this increases the chance of transmitting information between the nerve ends and the brain, and improves the control capability of finger muscles.

High, over time, the information processing capability of the left and right brains will be greatly enhanced, the response capability will be improved, and the fingers will be more flexible. Regular exercises will improve the coordination ability of both hands and the body. When reading the spectrum and playing the video at the same time, the attention will also increase accordingly, the attention will increase, and the memory will also increase. In addition, when the piano makes a sound, the ears transmit the sound signal to the brain, the brain needs to quickly determine whether the sound is correct, whether the volume is appropriate, and whether the length of the Note meets the music score requirements, therefore, practicing the accordion gradually speeds up the simultaneous response of the eyes, brain, fingers, and upper limbs, and accelerates the speed of thinking. With the deepening of the degree, the performance, imagination and expression ability will also be enriched accordingly.

Development and classification of Accordion

The accordion is a type of active-spring instrument. It is based on the pronunciation principle of the Chinese Leaf Spring.

In the lower half of the 18th century, the Chinese Sheng was introduced into Europe, and then some of the predecessor of the accordion began to appear in Europe, but most of them failed to form and were eliminated. The real hand-held organ was created in 1805 by the German people blerdch Buschman (1864-1822) and later by the Austrian people Demian (cyr?demian 1772-1847) on the basis of busman piano, he successfully improved and created the world's first Accordion named Accordion by collecting the great achievements of the predecessor of the Accordion at that time. Until today, the name Accordion is still used in Europe and America.

There are many types and specifications of the accordion. In terms of structure and morphology, the accordion can be divided into four categories: the whole scale accordion, the half scale accordion, the key-button accordion and the keyboard type accordion.

The fully scale accordion has a very simple structure, which is equivalent to adding a wind box to the harmonica. There are more than a dozen buttons in the right hand to play the music, and two chord buttons in the left hand to play the music. On the same button, the push-pull wind box emits two sounds of different heights (similar to the harmonica pronunciation). The piano has no straps and relies entirely on two hands. The biggest disadvantage of the whole scale accordion is that it cannot be changed, if you want to change the tune, you need to change another piano.

The half scale accordion is easy to adjust first. The number of buttons in the left and right hands is increased. In addition, the height of the push and pull windbox is different, so this music domain is very wide; the half scale accordion has no straps and is still played by the dual-handed violin.

The keyboard-style accordion (also known as the new half scale accordion) is equipped with a strap, which is a great relief for both hands. In addition, the sound of the push and pull cases is highly consistent, in this way, the change and application of the wind box have gained great freedom. The number of buttons in the left-hand part of the key-button type accordion is greatly increased and the arrangement is quite scientific.

In the 1960s S, the keyboard-type accordion began to appear.

From then on, the accordion is divided into two categories: button and keyboard. The two are developing in parallel. The structure of the left-hand keyboard of the keyboard-type accordion is exactly the same as that of the keyboard-type accordion, but the keyboard of the right hand is changed to a piano keyboard. Probably because of the piano, this improvement has made the European folk instrument accordion the most popular in the world.

According to the changes in the above several types of Accordion structures, we can see the major stages of the accordion development. Today's key-button accordion is popular in the Soviet Union and some Nordic countries, and the most popular in other countries and regions is the key-disc accordion.

Since the creation of the accordion, it has witnessed great revolutionary development in terms of manufacturing technology, playing skills, and professional music creation of the accordion. At present, the 185 division senior hand produced by the West Dutch piano plant... the remaining full text>
