To start, click the Stage.

You can add code to this Stage, just like you can to a Sprite.

(waves crashing)

To explore the other sounds in Scratch, click the choose sound from library button.

Once you've found the sound, remember its name because you'll need it to program it to play.

Next, program the sound to play.

Click the Sounds menu.

Drag out the play sound until done block.

Click the drop down, and then select the name of the sound you choose.

Click this block to run it.

(water bubbling)


To make the sound play repeatedly or in a loop, add a forever block.

To make the sound play at the start of your story, add a when flagged clicked block.

Click the flag to test it out.

(water bubbling)

If your sound isn't playing correctly, check that you selected the play sound until done block.

Now, it's your turn.

Click the Stage and the Sounds tab, and select a sound.

Play the sound using a play sound until done block, a forever loop, and a when flag clicked block.
