(三)低声部的产生规律就独弦琴的音响效果来说,基音(低声部)是泛音(主旋律声部)的依附声部,这个依附声部的产生,有其特定的规律性。 1.如果不改变弦的张力,在任何一个泛音位置上切弦挑弹,空弦基音都不变。所以当主旋律完全是自然泛音而没出现摇杆泛音时,低声部仅是原来空弦基音的重复,不形 (C) the law of the production of the low part of the monophonic sound effects, the pitch (low part) is the overtone (main melody part) attached to the Ministry, the dependent part of the production, has its own specific regularity . 1.
