The staff is the foundation upon which notes are drawn.
（这是五线谱）
The modern staff comprises five lines and four spaces.
（现代五线谱有五条线，四个间）
Every line or space on the staff represents a white key on the keyboard.
（每一条线或间都对应钢琴琴键上的一个白键）
Clefs assign individual notes to certain lines or spaces.
（谱号是指示某一个特定音符在五线谱上的位置的符号）
Two clefs are normally used: The Treble and Bass clefs.
（常用的两个谱号是高音谱号和低音谱号）
First, we will discuss the Treble Clef (also called the G Clef).
（首先我们来看高音谱号（也被叫做G谱号））G谱号）
Uh-oh. We just ran out of room to place notes, what happens now?
（哦啊，五线谱不够写了，怎么办？）
With the ledger line drawn, we can place the A.
（上加一线后，就可以再写一个A）
Next, let's discuss the Bass Clef (also called the F Clef).
（接下来，我们看一下低音谱号（也叫做F谱号））
The staff line in between the two dots of the clef is F.
（在低音谱号两点间夹的那条线上写的音符就是F）
We can now fill the rest of the staff with notes.
（把剩下的地方填好）
Notice how the two clefs are “joined” by the C (shown in red).
（注意看，C所在的那条线就是刚刚去掉的线（用红色表示），它连接了两个谱表）
