二胡有幾根琴弦呢?

發布日期:2017-03-02

二胡有幾根琴弦呢?

二胡有2根弦,因為它只有兩根弦,所以取名為二胡,二胡是現代的名稱,過去民間多稱它為南胡、胡琴、等,二胡看上去是一個物體,沒有什么感情可以表達,但是它一但經過不同的演奏人員在技術和藝術上的加工。就會變成一個很懂感情的東西。

二胡,又稱南胡,是中華民族樂器家族中,關於二胡最早的記載是在宋朝,是東方主要的擦弦樂器之一,主要部分有琴桿、琴軫、琴筒、琴托、千斤、蛇皮、琴碼、琴弓。弦有兩根,弦的訂音為D'A,琴弓類似小提琴之琴弓,附有馬尾毛,演奏時馬尾毛置于雙弦之中拉奏,這是全世界所有的擦弦樂器中,皆無的特點。

過去二胡大多用絲弦,由于絲弦具有伸縮性大、壽命短、發音不夠清越細膩等缺點,它已逐漸被鋼弦所淘汰,二十世紀六十年代以來,鋼絲弦使用日益普遍。

配套的二胡鋼弦應是一粗一細,粗的一根稱作內弦(也叫老弦),細的一根稱作外弦(也叫子弦)。內外弦分別系在相應的琴軸上,一般是先上內弦,再上外弦。選購琴弦一定要注意配套,不可兩根弦都為內弦或外弦,弦徑也不可懸差過大,更不可用其它彈撥樂器的琴弦來代替二胡弦。

內外弦采用同樣粗細的,就會產生兩弦張力不平衡,發音不協調,靈敏度差的問題;內外弦粗細比例過于懸殊。就會產生音色不統一,影響按指的問題;用彈撥樂器的琴弦來代替二胡弦,發音空而沉悶,失真度大,完全不符二胡的發音需要。
