Abstract

弓弦乐器三胡是一种使用弓弦摩擦可变长度的琴弦而发出悦耳动听音乐声音的乐器。传统的民族乐器二胡的琴弦只有两根——内弦和外弦,其低音部分只能低到d音,而人们唱歌的声音可以低到G音;比二胡的低音还低五度。低音的缺失极大地影响了我国民族乐器二胡的音乐地位和应用范围。本实用新型在传统的民族乐器二胡的基础上,使原来的音程向低音方向扩展了五度。从而克服了传统民族乐器二胡的不足,提升了胡琴这一传统的民族乐器的音乐地位,扩宽了应用范围。本实用新型的技术原理见说明书摘要附图:在传统的民族乐器二胡的外弦外增加一根低音琴弦(G弦或者比原来的内弦低五度的琴弦);在传统的民族乐器二胡的琴弓(弓子)上增加一股(束)弓弦并将其置于新增加的低音琴弦的外侧,其新增加弓弦的材料,可以是马尾,也可以是其它摩擦发声材料。

Description

弓弦乐器三胡
技术领域:是一种使用弓弦摩擦可变长度的琴弦而发出悦耳动听音乐声音的乐器,有琴(音)筒、鼓膜(发声蒙皮)、琴杆、琴弦、琴弦轴、千金(千斤)、码子和琴弓(弓子)。
背景技术:我国传统的民族乐器二胡的琴弦只有两根——内弦和外弦,其低音部分只能低到d音,而人们唱歌的声音可以低到G音;比二胡的低音还低五度。低音的缺失极大地影响了我国民族乐器二胡的音乐地位和应用范围。本实用新型在传统的民族乐器二胡的基础上,使原来的音程向低音方向扩展了五度。从而克服了传统民族乐器二胡的不足,提升了胡琴这一传统的民族乐器的音乐地位,扩宽了应用范围。
本实用新型技术的内容是:在传统的民族乐器二胡的外弦外增加一根低音琴弦(G弦或者比原来内弦低五度的弦),在传统的民族乐器二胡琴弓(弓子)的弓杆和常规弓弦之间增加一股(束)弓弦,并且将其置于所增加的低音弦外侧,其新增加弓弦的材料,可以是马尾,也可以是其它摩擦发声材料。其原理见说明书附图1。
附图说明:附图中1是琴(音)筒、2是琴杆、3是琴弦轴、4是千金(千斤)、5是琴弦、6是琴弓(弓子)的弓杆、7是新增加的弓弦、8是常规弓弦、9是鼓膜(发声蒙皮)、10是码子。
具体实施方式为:在原来二胡的琴弦轴处增加一个琴弦轴,也可以在原来二胡的适当位置增加适合的琴弦轴;将原来的码子增加适当的宽度,或者另加一个码子;加装一根低音琴弦(G弦或者比原来内弦低五度的弦),并且将其置于原来二胡外弦的外侧,同时将新增加的弓弦置于低音琴弦的外侧。此外,右手持弓子的方法是:弓杆末端夹持于拇指食指之间,中指顶住新增加的弓弦(根据需要控制弓弦的松紧,顶紧则可以使增加的低音琴弦发声),无名指顶住常规弓弦(根据需要控制弓弦的松紧,顶紧则可以使原有的二胡琴弦发声)。

Claims (2)

1.一种弓弦乐器三胡,有琴筒、鼓膜、琴杆、琴弦轴、琴弦、千金、码子和琴弓;其特征是比传统民族乐器二胡多一根低音琴弦。
2.根据权利要求1所述的弓弦乐器三胡,其特征是低音琴弦比传统民族乐器二胡的低音弦还要低五度。
