二胡在不同演奏手里表现出来的音色效果往往不同,甚至相差很大。探其原因——即二胡的发音问题。 什么是正确的发音呢?以下从四个方面讨论二胡演奏发音原理及其训练要求。 一、发音的基本观念: 二胡的发音是通过两手有机的配合、协调、自然的运动,引起音源琴弦的振动,转换为与之相连的蛇皮、共鸣箱的共震而发出声音。声音发出后可根据需要加以改变,其基本形态是增强或减弱,同时琴弦运动的频率、振幅、把位变化引起琴弦振动率的衰减而发生的变化产生了二胡的音韵。
Erhu performance in different hands show the sound effects are often different, even a great difference. Exploring the reason - erhu pronunciation problem. What is the correct pronunciation? Here are four aspects of erhu playing pronunciation principles and training requirements. First, the basic concept of pronunciation: Erhu pronunciation is through the hands of organic cooperation, coordination, natural movement, causing the vibration of the sound source strings, converted to connected with the snakeskin, resonance box and the sound of the earthquake. After the sound is emitted, it can be changed according to the need. The basic shape of the sound is enhanced or weakened. At the same time, the frequency and amplitude of the string movement, and the change of the bit position causing the attenuation of the vibration rate of the string produce the erhu sound.
