笔者通过长期实践,制成一种构造简单而又便于学习的四弦板胡(见图1)。其结构特点如下: 1.在原板胡头部的外侧加两根弦轴,让其象小提琴那样两两左右排列。 2.将琴筒以上二寸半的范围内的琴杆外侧削去半边。运弓时,弓毛与内外弦直交,与另两弦斜交(斜交的轨道恰与原板胡相同)。 Through long-term practice, the author made a simple and easy to learn four-string plate Hu (see Figure 1). Its structural features are as follows: 1. In the original plate Hu head outside of two string axis, so that it is arranged around the violin. 2. Cut the half of the outer side of the rod within two and a half inches above the cylinder. When bowing, the bow hair is perpendicular to the inner and outer strings, and the other two strings are skewed (the skewed orbit is the same as the original one).
