Voice over & Music

For my short film, I have put my voice over and music on. Obviously, when the parts of the film where the voice over is, I have split the music clip where there is a voice over segment and made the music to 6% on the volume. 
When the voiceover disappears I have made the music slightly louder as that will be the main audio for that small part of the film. I put this on 17%. The voiceover is always 40% as I don't want the music in the background to be completely neglected.
