目前使用的高胡最重要的缺点是:①音色太亮,不与拉弦乐组起交响,而与唢呐起交响。②有效音域太窄。鉴此,我改革试制了三弦高胡(见图),其结构如下:1.琴筒为适应扩大音域、音量的需要,琴筒前口制成扁八角形;后口比前口大,为正八角形;琴筒内有喉管;并采用了立体音窗。此外,琴筒装有空心琴托及前后反射板。 The most important shortcomings of Gao Hu currently used are: ① The tone is too bright, not symphonic with the string strings, but symphonic with the suona. ② effective range is too narrow. In view of this, I reform the trial of the Sanxian Gao Hu (see photo), the structure is as follows: 1. The piano in order to adapt to the expansion of the sound field, volume requirements, the front of the Qin tube made flat octagonal; Is octagonal; piano tube throat; and the use of stereo windows. In addition, the piano is equipped with a hollow case and front and back reflector.
