这是个很有趣的问题。在十二平均律里,这两个音是在一个音位上,没有什么高低之分。但在实际运用上,却有了高低。这是为什么呢? 我们知道不稳定音在运动时,都有一种倾向,那就是要求解决。解决到哪里去呢?解决到最近的半音的方向上去。比如7——,『7』音要解决到最近的半音的『i』音上去。而如果是『2』音,它距离上下相邻的都是一个全音。距离相等,则解决到上下两 This is a very interesting question. In the twelve average law, these two sounds are in a phonemic, there is no distinction between high and low. However, in practical application, there is a high or low level. Why is this? We know that there is a tendency for unstable sounds to move, which is to ask for solutions. Where to solve it? Solve the direction of the recent semitones. For example, 7 -, “7” sound to solve the recent semitone “i” sound up. And if it is “2” sound, it is up and down adjacent to a full-tone. The same distance, then solved up and down two
