【摘要】：二胡作为一件民族乐器经历了近千年的自身变革,这种变革是自身内部的循环发展。然而,在科技软件发达、产业技术升级、创新产业蓬勃发展的今天,越来越多的民族乐器开始尝试与科技进行结合,由声学乐器向电声乐器进行转变。然而在民族乐器电子化方面,目前还没查到与之相关领域的研究成果。本文围绕着二胡与电子音乐的三个具体问题进行研究:第一,关于设计一把MIDI二胡的乐器构想。在此基础上,因个人能力有限,故借助现有的MIDI信号转换器——罗兰GI-10,实现MIDI二胡实时激发电子音色的具体实施方法研究。第二,关于二胡的音域、音色、演奏技法与所激发的电子音色的匹配度以及在实时演奏中的若干问题;实时激发后在电脑软件采样器中制作音色功能的具体映射与搭建方法;第三,根据已有原声二胡实时激发电子音色方法为'二胡与[513教室]电子乐团'创作的两部作品,对前文所提及的技术在创作中实践,并对应用的作曲技术与激发技术进行具体分析。通过以上分析与研究发现,二胡与电子音乐之间实时交互的方式,可以不再只是通过样本采样和样本音频编辑的传统方法进行音乐创作。将二胡变成一件音色拓展、演奏信息识别转换、激发效果器参数的复合功能乐器,将更加有利于电子音乐的交互式创作。这些多维度的功能在MIDI二胡的激发过程中,皆可实现。由此可见,通过以上研究可以开拓二胡作为民族拉弦乐器的单一角色,触及至更加广阔与多维度的电子音乐领域中进行更加深入的探索。
[Abstract]:Erhu, as a national musical instrument, has experienced the transformation of itself for nearly a thousand years, which is its internal circular development. However, with the development of science and technology software, the upgrading of industrial technology and the vigorous development of innovation industry, More and more national musical instruments are beginning to try to combine with science and technology, from acoustic instruments to electric instruments. However, in the electronic aspects of national musical instruments, This paper focuses on three specific problems of erhu and electronic music: first, about the design of an MIDI erhu musical instrument. On this basis, because of personal ability is limited, Therefore, with the help of the existing MIDI signal converter Roland GI-10, the concrete implementation method of real-time firing electronic timbre of MIDI erhu is studied. The matching degree of playing technique and the electronic timbre stimulated and some problems in real-time playing; the concrete mapping and building method of timbre function in computer software sampler after real-time excitation; third, According to the two works of 'Erhu and [513] Electronic Orchestra, which have been used to stimulate the electronic timbre of the original erhu in real time, the techniques mentioned above have been put into practice in the process of creation. Through the above analysis and research, it is found that the real time interaction between erhu and electronic music, It is no longer possible to create music only through the traditional methods of sample sampling and sample audio editing. The erhu can be turned into a composite functional instrument that expands the timbre, plays information recognition and conversion, and stimulates the parameters of the effector. These multi-dimensional functions can be realized in the process of stimulating MIDI erhu. Thus, through the above research, we can explore the single role of Erhu as a national string instrument. Touch to a broader and more dimensional field of electronic music for more in-depth exploration.
