钢琴在自己的展开主题中,演奏出一段贯穿在两行五线谱中的重奏.

Noted in two staves , the piano plays a reprise of its own opening theme.

这五条线叫五线谱，五线谱在两个轴之间：上下和左右。

These five lines are called a staff, and a staff operates on two axes: up and down and left to right.

五线谱上音符越高，表示音调越高。

The higher up on the staff a note is placed, the higher the pitch.

不过我给你的信值得写在五线谱里呢。

But my letter to you is worth to be written there.

因此我们怎么样把这88个音符压缩到五线谱上呢？

So how do we condense 88 notes onto a single staff?

你应该有注意到五线谱上有几条小线将乐谱分成几个小段落。

You might have noticed that across the length of a staff, there are little lines dividing it into small sections.

五线谱的前身可追溯到中世纪的纽姆记谱法及有量记谱法。

Staff can be traced back to the Middle Ages, the predecessor of the Niumu notation and the amount of notation.

再回到五线谱。每条线，还有线与线间的空格都代表一个音调。

Going back to the staff, every line and every space between two lines represents a separate pitch.

希望的人间回响着青春旋律， 学子的成长就是五线谱音符。

I hope the world echoing melody of youth, the growth of students is to read music notes.
