摘　　要：MIDI技术具有灵活的演奏形式与超强的编辑能力,自20世纪80年代诞生以来,计算机音乐因为有了这个统一的接入标准以及在音乐制作上的便利性而得到了极大的发展。MIDI的主要特点在于其是一种数字文件,而非音频文件,是一种描述性的数据“音乐语言”,仅仅是记录了演奏乐曲的信息,因而占用的存储空间极小且便于编辑、修改。MIDI音乐主旋的提取除了在技术上的实践应用,更重要的是有利于音乐数据库的构建,对于多音轨MIDI音乐主旋律提取方法的探析有着一定的实践意义。MIDI technology has flexible performance forms and super editing ability.Since its birth in the 1980s,computer music has been greatly developed because of this unified access standard and the convenience in music production.The main feature of MIDI is that it is a digital file,not an audio file.It is a descriptive data"music language",which only records the information of playing music,so it occupies very little storage space and is easy to edit and modify.In addition to the practical application in technology,the extraction of MIDI music theme is more important for the construction of music database.It has a certain practical significance for the analysis of multi track MIDI music theme extraction methods.
