二胡有几根琴弦呢?

发布日期:2017-03-02

二胡有几根琴弦呢?

二胡有2根弦,因为它只有两根弦,所以取名为二胡,二胡?#31373;?#20195;的名称,过去民间多称它为南胡、胡琴、等,二胡看上去是一个物体,没有什么感情可以表达,但是它一但经过不同的演奏人员在技术和艺术上的加工。就会变成一个很懂感情的东西。

二胡,又称南胡,是中华民族?#21046;?#23478;族中,关於二胡最早的记载是在宋朝,是东方主要的擦弦?#21046;?#20043;一,主要部分有琴杆、琴轸、琴筒、琴?#23567;?#21315;斤、蛇皮、琴码、琴弓。弦有两根,弦的订音为D'A,琴弓类似小提琴之琴弓,附有马尾毛,演奏时马尾毛置于双弦之中拉奏,这是全世界所有的擦弦?#21046;?#20013;,皆无的特点。

过去二胡大多用丝弦,由于丝弦具有伸缩性大、寿命短、发音不够清越?#25913;宓热?#28857;,它已逐渐被钢弦所淘汰,二十世纪六十年代以来,钢丝弦使用日益普遍。

配套的二胡钢弦应是一粗一细,粗的一根称作内弦(也叫老弦),细的一根称作外弦(也叫子弦)。内外弦?#30452;?#31995;在相应的琴轴上,?#35805;閌窍?#19978;内弦,再上外弦。选购琴弦一定要注意配套,不可两根弦都为内弦或外弦,弦径也不可悬差过大,更不可用其它弹拨?#21046;?#30340;琴弦来代替二胡弦。

内外弦采用同样粗细的,就会产生两弦张力?#40644;?#34913;,发音不协调,灵敏度差的问题;内外弦粗细比例过于悬殊。就会产生音色不统一,影响按指的问题;用弹拨?#21046;?#30340;琴弦来代替二胡弦,发音空而沉闷,失真度大,完全不符二胡的发音需要。
