怎样挑选二胡?如何在网上挑选一把好二胡

发布日期:2017-06-07

      在互联网?#20309;?#26085;益发达的今天,不只一些生活用品可以在网上买,就连二胡这样的传统?#21046;饕材?#22312;网上订购了。网购的最大好处就是?#40644;频?#22495;限制以及一个更合理的价格。

      如今,喜爱二胡的人越来越多,但如何才能买到一把令人称心的二胡?优秀二胡应具备什么样的要素?怎样挑选二胡?从网上购买的二胡到底品质如何呢?下面我们就来谈谈二胡品质的几个重要?#38382;?br style="word-wrap: break-word;">
       二胡是胡琴家族中的重要成员之一,琴筒由木或竹制成,一端蒙蟒蛇皮,两根弦、马?#24067;?#20110;两弦之间拉奏。它的音色优美、柔和、表现力丰富。现在的二胡已发展到可以演奏大型协奏曲、国外移植曲目甚至演奏现代派的音乐作品,演奏技巧可以与小提琴相媲美。二胡是民族弓弦类?#21046;?#20013;使用最普遍、最具中国民?#21046;?#36136;和特点、最有韵味的?#21046;鰲?#20108;胡在民乐队中的地位尤为突出,是民族乐队中的?#21046;?#20043;王,也是江南丝竹、广东音乐中的主要?#21046;鰲?br style="word-wrap: break-word;">
      1、共振是否好
     挑选一把好二胡首先是看材料,普通柴木密度不够,不适宜制作二胡;紫素?#30784;?#20044;木等太硬的木头也不见得是最好的制琴材料。老红木制作的二胡,里边的树脂干透了,它上面的棕眼就像人皮肤上的寒毛孔一样,能?#40644;?#21040;调节内部音色振动的作用,如果都?#32654;?#23553;死了,它的振动?#31570;换?#22909;。让皮板的振动通过筒子到担子三位一体贯通了,这是一把好二胡的第一要素。检验二胡三种一体是否贯通了,办法是拉空弦时,虎口、琴担子、筒子是否有振动感,共振好的二胡托板放在腿上?#26448;?#24863;觉到振动。

      2、灵敏度
      挑选二胡时,用大力气推拉弓,看其爆发力和声音的灵敏度如何。推拉弓使劲却不出声,?#31570;?#26159;好的二胡。轻拉时,不管什么角度,没?#23567;吧成場?#30340;声音,就证明这琴“抗劲?#20445;?#26159;一把不错的二胡。

      3、音量大小
      音量是否饱满、浑厚、音色瘪不瘪?是在筒子外边还是筒子的皮子上发声?#31354;?#27491;的二胡发声要有膛音,即在担子的中间发声为最好,这种声音穿透力强,声音打得远。

      4、有没有二胡的韵味
       北方的二胡音色明亮,与南方二胡相比,韵味稍逊(目前北方的一些制琴作坊?#26448;?#21046;作出韵味很足的二胡)。当然,也有许多演奏家专门?#19981;?#25289;北方的二胡,因为每个人都有自己的追求和喜好。

      5、音色是否甜美,是否能够打动人心
      音色优美的二胡拉出来的音乐能够让人心动,能在听众中产生共鸣,百听不厌,给人以美?#21335;?#21463;。

      6、里外?#19994;?#36136;量是否统一
      里弦和外弦应统一,用弓拉就可听出来,里外弦要匹配,声音要各谐。

      7、上下把调试
      调试就是感觉音量、音阶、音色是不是均衡,上把好,下把不好也不行,过渡时?#23567;?#22350;?#26412;筒?#22909;,要拉着顺畅。

      8、检验泛音
      二胡演奏中要用泛音,因此在选购二胡时要看这把二胡的泛音点清楚不清楚、干净不干净。
