Unplugged - Songwriting with Parameters

This is the song writing lesson. The written

Music is a lot like a computer program.

The written notes and words tell the singer exactly what to do.

Some parts of music are used over and over again. We call this the chorus.

In a computer program, the parts of the program used over and over again are called functions.

When you read song lyrics, and it says the word "chorus", do you sing the word chorus?

No, you look at the top of the page to see what words make up the chorus.

In this lesson, you'll learn a silly little song called Little Bunny Foo Foo.

The song has a chorus that you will sing several times over and over again.

A function is a piece of code that you can call and use over and over again.

It makes programming easier and more efficient,

so you don't have to write out the steps of your function over and over again.

You can just write it once!
