In this video you'll add sound to your commercial to make it more dynamic and exciting.

Click on the Sounds tab and choose a sound to play in the background of your commercial.

Click the Sounds Vimeo and drag out a play sound until done block.

Click on the block to try it out.

Sounds good.

Add a forever block so that the music will play continuously while the commercial runs.

Try it out.

Now the music plays continuously but only when the block stack is clicked.

Add a when flag clicked block to make the music and the commercial start at the same time.

Try that.

Awesome, now the music starts when the commercial begins.

It's important to use the play sound until done block here instead of the play sound block because the until done ensures that the sound plays to the end before it plays again.

Using the play sound block instead makes the sound stutter or play incompletely.

This sound seems a little loud for background music.

Add a set volume to block after the when flag clicked block and tinker with its value until you like the volume of the music.

Nice job.
