I have another great tip from MG/YA writer Melanie Woods. Melanie's past tips include #127 and #133, which deal with character development and voice, respectively. Here's her newest!
WRITING A SONG IN THE MC’S POV
It's not an uncommon thing for preteens and teens to write songs from time to time. (I reckon it's safe to say that most of the writers reading this wrote a few poetic, melodramatic songs during their childhood. I know I did.) If you visit a site where teens post poems and lyrics (TEEN INK is one) you’ll find numerous songs about crushes, being betrayed by a best friend, or holding emotions in and not being able to let them out. Essentially, writing songs is a method to share thoughts and emotions in a creative way.
"But how does this help me as a writer?" you might ask. This exercise will aid you to see through your MC's eyes better, and be able to pinpoint where the character's emotions and concerns are headed in the scene.
