We have the pulse being slowed down and almost like a law of physics or something, now comes a reaction- now John Kander makes the music accelerate so let's watch a wonderful example of accelerando here.
这里我们听到节奏慢了下来,但是,与物理类似,反作用出现了,现在约翰·肯德尔加快了音乐的节奏,让我们看到了一个渐速音的好例子
You cannot have a spring pulled only at one side, because then it will then accelerate with infinite acceleration in that direction.
