I find that when I’m aiming for a certain tone or vibe in my writing, it helps a lot to be listening to music that evokes the same feeling I’m going for. It puts my brain into the right gear and the visions of what I need to write come a lot easier.
What are you trying to write? If you imagine the scene as taking place on TV, what music would be playing in the background? Find something similar, and listen to it while you write. I can bet you it will improve your productivity.
I’ve been listening to the soundtrack for Under the Skin a lot lately. If you listen to it, I bet you can guess what kind of vibe I’m trying to give my story. The music certainly helps inspire ideas. Give it a try!
