在管乐演奏中,往往通过舌头达不到一定吐音速度时,就需借助双吐这种演奏方法。简单来说就是TU、KU、TU、KU交替,第一下是用舌头来接触大管的哨片发出的声音,第二下是通过气流阻断声音,达到吐音目的,这种演奏技巧对于一般的管乐器如:小号、长笛等是有一定的难度的,那么对于大管来掌握这种技术更是难上加难,因为哨片是放在口腔里面的,舌头活动范围是有限的,所以我们要掌握这种技巧是要花大时间的。开始练习的时候我们一般建议演奏者先唱之后在哨片上练习吐和苦,通过一段时间的练习达到目的后再到乐器上去练习,很多演奏者在练习的过程中会遇到一个问题,就是舌头往往会对某一种速度控制不好,手指与舌头的协调性也没有配合好,更不要说什么吐音质量和音色啦!所以建议演奏者开始用节拍器慢慢来练习,通过一段时间的努力练习,相信会有很大的进步。 In the music performance, often through the tongue can not reach a certain spit speed, you need to resort to double spit this method of playing. In simple terms is TU, KU, TU, KU alternate, the first is the tongue to contact with the tube of the reed out of the sound, the second is through the air flow to interrupt the sound, to spit sound purposes, this performance skills for General wind instruments such as: trumpet, flute and so there is a certain degree of difficulty, then for the big tube to master this technology is even harder, because the reed is placed in the mouth inside, the scope of the tongue is limited, So we have to master this technique is to spend a lot of time. At the beginning of the practice, we generally recommend that the performer practice vomiting and biting on the reed after singing first, and after a period of practice to achieve the purpose, he will practice on the musical instrument. Many performers encounter a problem during the practice, that is, the tongue Often a certain kind of speed control is not good, the coordination of the fingers and the tongue did not cooperate well, not to mention what the vocal quality and sound it! So recommended that the player began to practice with metronome slowly, through a period of time Work hard, I believe there will be great progress.
