他们的乐器比我们的钢琴更富于表情，更灵敏，通过弓法和呼吸，他们可以更多的利用微小的延迟、悬念和渐速音。

Their instruments are more expressive and sensitive than ours, and through bowing and breathing they can make much more use of slight delays, suspenses and accelerandos.

Okay. So at that point the music begins to speed up with the accelerando.

嗯,从音乐的那一点开始,节奏随着渐速音加快

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
