Though I wasn't smart enough to figure this out at the beginning of my novel crafting life, writing scenes to specific music has given an intuition to my character's actions and comments--a zest that was missing before. It helped to sit down one afternoon and think through what style of music--and why--would appeal to the people coming to life on my pages. Some characters love music, love to dance, and can't hear a tune without tapping their fingers. Other don't even acknowledge that they recognize a particular singer or group. Much like personality profiles help to craft a character, music has a role to play too. Plus, it's fun learning this aspect of a character and using that knowledge to make the story more authentic.
