摘要
把传统的"拉伸式"千斤改革为"扣压式"弹性千斤,使空弦音色厚实富有弹性,且利于揉弦。特别是在分析二胡泛音原理之后,在"扣压式"千斤基础上设计了能拓宽音域,使二胡泛音成倍增加的装置。
In this paper, we have done improvement which reform the ＂stretching＂ Qian-jin into the ＂buckle-press ＂ flexible Qian-jin. This improvement makes the tamber of empty string thick and elastic which is benefit for rubing strings. Especially after analysing the theory of Er-hu overtone, we designed this instrument which can increase the overtone in the base of ＂buckle-press ＂ Qian-jin.
