A great way to show clients how a musical score may sound against their project without actually hiring a composer is to use mockups.  Mockups are essentially existing projects with all the music stripped out and re-scored.

The project below is a Bethesda production (animated by Blur studios, who I love!) called The Elder Scrolls Online.  It’s a massive online multiplayer game that was released not too long ago.  I’ve stripped most of the sound effects and the music and scored my own version to demonstrate how many different approaches can be used with any given project.
