很不幸这种表示旋律的方法忽略了音符的时值，但这项编程任务是关于音高的，与时值无关。

It is unfortunate but true that this representation of melodies ignores the notion of musical timing; but, this programming task is about notes and not timings.

什么是全音符,这些符号又都是什么呢,这些就是简单代表了持续时间,因此我们这里有一套符号语言,来代表横轴,就是时值的那条轴

What the whole note is, what all these symbols are are simply representations of duration so we have a symbolic language here that's going to represent the horizontal axis the axis of duration.

Notes are simply longer, held longer.

音符的时值延长,单纯把持续时间延长

We talk in terms of high pitch and low pitch although we'll fine tune that next time, and then we have this idea of duration or time, which we tend to write out in symbols that move from your left to right.

我们是从高低方面来谈论音高,即使我们将于下次讲解曲调的问题,我们已经有了音符时值或时间的概念,我们倾向于用符号来表示,时间是从你的左边向右边移动的
