Remember: every layer or caption always has at least 2 keyframes. That
means by default, you can make two changes to your soundtrack volume.
The first when the slide begins (Keyframe 1) and the second when the slide
ends (Keyframe 2).

4. Select Keyframe 1. At the bottom of the Motion & Audio pane,
locate the Soundtrack control slider and change the volume to
10% then click OK to apply the change.
Now back in the Workspace, click on slide number 2 and press play in the
preview.
As the transition between those slides begins, you'll hear the soundtrack
volume drop from 100% to 10%. How long that takes will be determined by
the transition length.
As slide 3 continues to play, the volume will gradually return to full volume.
This happens because we did not change the volume of Keyframe 2. The
volume at that point is still set to be 100% (the default master volume of the
Soundtrack).

If you press the TAB key on your keyboard to open the Timeline View,
you'll see how the keyframed value has affected the volume of your
soundtrack.
