1860 年 ，德国著名单簧管演奏家贝尔曼 （Carl.Baerman

In 1860, the famous German clarinet player Carl. Baermann felt that Miller’s improved clarinet still had some shortcomings, so he cooperated with the musical instrument maker Ottens Tanner and began to figure out how to improve the performance of the Miller clarinet. Some unreasonable fingerings were later invented to apply the advantages of the ring key and the long shaft connecting rod to the musical instrument. After that, Bellman's clarinet continued to be used until the beginning of the 20th century. Its characteristic is that there are fewer holes in the tube, which makes the tone of the tube cleaner, but its fingering is more troublesome than the Pom style. When playing music before the late romantic period, Miller and Bohm clarinet performed similarly. However, in the performance of the late romantic works, the Miller clarinet is worse than the Bohm style in terms of operability and volume tension. In 1900, Oude began to develop a new system for these two types of clarinets. He hoped that the clarinet would be clean in tone and could be simple and convenient in the use of fingering, which could combine the strengths of the two models and avoid the shortcomings of the two. In 1920, he developed the Ou-German system, the clarinet of this system avoids the problem of French instruments with too low bass and high pitch. It has 5 ring keys and 27 buttons, and the convenience of fingering is equivalent to that of French, but it is not perfect. Some of its sound holes are far away from each other, so it can be played by people with small palms. Not too advantageous.

In 1860, Carl. Baermann, a famous German clarinetist, sensed that Miller's improved clarinet still had some shortcomings, so he worked with the instrument maker Oats tanner to come up with ideas on how to improve some unreasonable fingering on Miller's clarinet, and then invented the advantages of using ring keys and long shaft rods on musical instruments. This clarinet from Berman has been in use since the early 20th century. It is characterized by fewer holes in the tube, which makes the tone aspect of the tube cleaner, but its fingering is more troublesome than The Pom style. Miller performed much like a Pom-style clarinet when playing music from the late romantic period. But when playing romantic later works, Miller's clarinet is a little less operational and volume-stressed than the Pomian. In 1900 Ode began to develop new systems for these two models of clarinets, and he hoped that the clarinets were relatively clean in tone and could be easily used in fingering to avoid the shortness of the two. In 1920, he developed the European-German system, a clarinet that avoided the problem of French instrument bass being too low on pitch. It has 5 ring keys and 27 keys, the convenience of fingering is also comparable to French, but it is not perfect, some of its sound holes between the distance is far, for some people with too small palms to play is not too favorable.

In 1860, the famous German clarinet player Behrman（ Carl.Baermann ）Feeling that Miller's improved clarinet still had some shortcomings, he began to work with instrument maker otanstaner to figure out how to improve some unreasonable fingering on Miller's Clarinet, and then invented to apply the advantages of ring key and long shaft connecting rod to musical instruments. Behrman's Clarinet was used until the beginning of the 20th century. Its characteristic is that it has fewer holes on the tube, which makes the tube more clean in timbre, but its fingering is more troublesome than Bohm style. When playing pre romantic music, Miller and Bohm clarinets have similar performance. But in the late romantic works, Miller's clarinet is worse than Bohm's in operability and volume tension. In 1900, oder began to develop a new system for these two types of clarinets. He hoped that the clarinet would be clean in timbre and easy to use in fingering, so as to integrate the advantages of the two and avoid the disadvantages of the two. In 1920, he developed the European German system, which avoided the problem of too low bass and too high treble of French instruments. It has five ring keys and 27 keys. The convenience of fingering is similar to that of French style, but it is not perfect. Some of its sound holes are far away from each other, which is not very beneficial for some people with too small palms to play.<br>
