Accordion - (Cyrill Demian 1829) - 手风琴 アコーディオン 아코디언 अकॉर्डियन

Cyrill Demian, a piano maker from Vienna with Armenian-Romanian roots, submitted a patent for a new instrument called the ACCORDION on May 6, 1829.

On May 23, 1829, he received the patent for his new instrument, the accordion.

The accordion works with a free reed technique that had been developed in Europe shortly before (1780-1821).

(Free reed instruments have existed in Asia for at least 3000 years, but a similar technique was only developed in Europe at the end of the 18th and beginning of the 19th century)

The first accordion had 5 keys and each key could play 2 chords.

With the key open: one chord when the bellows were pressed together, and another chord when the bellows were pulled apart.

A chord consists of 5 reeds attached to a metal plate.

It was a small instrument with a wide range that could be played by almost anyone, including amateurs.

Shortly before this, the harmonica was invented, which also worked with the newly developed free reed technique and was probably the model for the invention of this instrument.

So the accordion is a mouth harmonica that can be played with bellows, which also gave the instrument the name hand harmonica in German-speaking countries.

1829 年 5 月 6 日，来自维也纳、有着亚美尼亚-罗马尼亚血统的钢琴制作师 Cyrill Demian 提交了一份名为 ACCORDION 的新乐器专利。

1829 年 5 月 23 日，他的新乐器手风琴获得了专利。

手风琴采用的是欧洲在不久前（1780-1821 年）发展起来的自由簧片技术。

(自由簧片乐器在亚洲至少已有 3000 年的历史，但类似的技术直到 18 世纪末 19 世纪初才在欧洲发展起来）。

第一架手风琴有 5 个键，每个键可以演奏 2 个和弦。

在琴键打开的情况下：当风箱压在一起时弹出一个和弦，当风箱拉开时弹出另一个和弦。

一个和弦由连接在金属板上的 5 个簧片组成。

这种小型乐器音域宽广，几乎任何人都能演奏，包括业余爱好者。

在此之前不久，人们发明了口琴，它也采用了新开发的自由簧片技术，可能是这种乐器发明的原型。

因此，手风琴是一种可以用风箱吹奏的口风琴，在德语国家，手风琴也因此得名。
