本世纪中叶,国际音乐界有一项重大的改革。但系于实践中逐步改进,并无理论报导,所以鲜为人知。这就是“律制改革”,由原先的五度相生律改用纯律。这种将大三度调窄,将小三度阔宽的微小改动,却使声乐、管弦乐的所有领域,在和声的协和、纯净度上大大的改观,音响效果步入了一个崭新的领域。但原苏联、东欧诸国都没有改革,这也影响到我国。更加不幸的是我国几千年来一直是纯律传统,古代的编钟,现代的民间音乐,都可以说明这一点。也就是说,西方跟着我们的脚步来了,我们却将别人淘汰 In the middle of this century, the international music industry has a major reform. However, it is rarely known in the literature that it is gradually improved in practice and has not been reported in theory. This is the “legal system reform”, from the original five-phase law to pure law. This will be the third major narrowing, the small changes of three degrees wide and wide, but the vocals, orchestral in all areas, harmony and purity of harmony greatly improved the sound effects into a brand new field. However, there were no reforms in the former Soviet Union and Eastern European countries, which also affected our country. What is even more unfortunate is that our country has been a pure law tradition for thousands of years. Ancient bells and modern folk music can all illustrate this point. In other words, the West followed our footsteps, but we will eliminate others
