Music is a writer's best friend. There we go. It can inspire you to write, or can make you redirect your work. Music is the closest thing this world has to magic, basically. But what most people don't do is write with music. This means that you find a song that goes with your book (happy, sad, anything) and rewrite the lyrics of the song and into your book. Maybe you could even put the song lyrics (with mention of the artist) into the writing?! I can do wonderful things if you do that.
Here are some tips on what to do if you're writing with music:
Step 1) Get an idea about what you want to write.
Step 2) Find a song with the same idea.
Step 3) Listen to the song over, and over, until you get an idea.
Step 4) Write the best you can while listening to that song.
Step 5) Repeat.
This is what I do when I write my stories/poems. It's an effective way of getting your creativity flowing. I hope these help.
