First Dad let me pick out the wood

首先，爸爸让我挑选木材。

旁白 neutral

This is an important step since the wood helps make the sound

这是很重要的一步，因为木材有助于发声。

旁白 neutral

Woods like spruce and cedar are often used to make guitars

云杉和雪松之类的木材常被用来制作吉他。

These woods are strong, and they vibrate easily

I chose a piece of spruce with a nice pattern in the wood

旁白 neutral

But this piece wasn't ready to cut yet

We had to dry it first

If the wood is not dry enough, it might shrink and crack after the guitar is made

如果木材不够干燥，做成吉他后可能会收缩开裂。

When the wood was ready, it was time for the next step

I traced outlines on the wood

旁白 neutral

Then Dad used a machine to cut out pieces for the sides, front, back, and neck

Have you ever wondered how a guitar's curved sides are made?

Dad took the pieces for the sides and quickly dipped them in very hot water

爸爸拿起侧板部件，快速地浸入很热的水里。

旁白 neutral

This made the wood easy to bend

旁白 neutral

Then we had to clamp the pieces to a mold

然后，我们得把部件夹在一个模具上。

旁白 neutral

This kept the wood bent as it dried

这样能在木材干燥时保持弯曲的形状。

旁白 neutral

While the sides were drying, we cut an opening in the neck for a long, thin piece of metal

侧板干燥的时候，我们在琴颈上切了一个口子，用来安放一根细长的金属片。

旁白 neutral

The metal supports the neck and makes it strong

这根金属片支撑着琴颈，让它更结实。

旁白 neutral

The next step was gluing

下一步是粘合。

旁白 neutral

We glued all the pieces tightly together, then left them to dry overnight

When the glue was dry, we sanded all the surfaces of the guitar to make them smooth

My guitar sounds great too!

The strings vibrate when I pluck them, and this produces sound

The length of the string affects the sound

If the string is long, the sound is low

如果琴弦长，声音就低。

If it is short, the sound is high

旁白 neutral

When I play the guitar, I can press my finger on a string to make it shorter and change the sound

These are small strips of metal across the guitar's neck

The strings alone don't make much sound

只有琴弦本身，发不出太大的声音。

旁白 neutral

That's where the body of the guitar, or sound box, plays an important role

这时候吉他的琴身，也就是共鸣箱，就起到了重要的作用。

旁白 neutral

When a string is plucked over the hole in the sound box's top, the sound becomes louder
