1
00:00:04,880 --> 00:00:07,720
This is the song writing lesson. The written

2
00:00:08,060 --> 00:00:10,060
Music is
a lot like a computer program.

3
00:00:10,780 --> 00:00:14,520
The written notes and words tell the singer exactly what
to do.

4
00:00:14,760 --> 00:00:19,720
Some parts of music are used over and over again. We call this the chorus.

5
00:00:21,040 --> 00:00:27,000
In a computer program, the parts of the program used over and over again are called functions.

6
00:00:28,360 --> 00:00:34,120
When you read song lyrics, and it says the word "chorus", do you sing the word chorus?

7
00:00:34,620 --> 00:00:39,320
No, you look at the top of the page to see what words make up the chorus.

8
00:00:39,960 --> 00:00:45,300
In this lesson, you'll learn a silly little song called Little Bunny Foo Foo.

9
00:00:46,400 --> 00:00:50,480
The song has a chorus
that you will sing several times over and over again.

10
00:00:51,440 --> 00:00:55,580
A function is a piece of code
that you can call and use over and over again.

11
00:00:56,240 --> 00:00:58,475
It makes programming easier and more efficient,

12
00:00:58,920 --> 00:01:02,060
so you don't have to write out the steps of your function over and over again.

13
00:01:02,540 --> 00:01:05,360
You can just write it once!
