2. Designing Sound Effects and Composing Music for Movies


Welcome to CS First Music & Sound.

Today, you will learn about sound effect design and music composition in movies and games.

Then, you will build your own animation or game and add sound.

When you work on the core project for today’s club, you will choose sound effects that will play when one sprite bounces into other sprites.

At the end of today’s session, you’ll get a chance to customize and program your own add-ons.

First, check out these clips about the exciting field of providing sound and music to movies and games.

As you saw in the videos, there are many types of computer science and technology skills that go into sound effect design for movies and games.

Today’s project will give you a chance to explore how adding different sound effects can change the personality and feel of a character or scene.

You can choose to either work on the Sound Effects you just saw, or to go back to the add-ons page from last session’s Music Video project and continue to build add-ons for your music video.

Now it's your turn: If you want to work on the music video, click the "Music Video Add-Ons" link on this page.

If you would like to work on the new Sound Effects program, click on the "Music Effects" starter project link that is on the same page as this screen cast.

Then, click the Remix button.

This will contain some code to get you started.

But, don’t forget to sign into scratch so that your program is saved to your account.

Add a sprite, which will be hit by other sprites.

This sprite will be the main character in your movie.

After you complete these steps, click the green arrow to go on to the screen cast.
