Some writers crave the soundtrack of a busy coffee shop while they write. Others make playlists for each project, or will listen to the same song on repeat while writing a specific scene.
Personally, I prefer silence when I write, though I’ve started making playlists for each project with songs that remind me of certain characters or scenes. But since I’ll be hosting write-ins at the library in November (which is by no means silent, though the room we’ll be using is pretty quiet), I thought it might be good to come up with some light background music to play. I’ll let attendees vote on whether they want the music or not, and of course they’re welcome to bring headphones if they have their own music they want to listen to, but I want to offer something beyond silence. Most public meet-up spaces have at least some background noise, and some people need that to settle into a rhythm.
Two of my favorite groups for instrumental music right now are 2Cellos and The Piano Guys. Both groups perform instrumental covers of popular songs. My favorites right now are 2Cellos’ cover of U2’s “With or Without You“, and The Piano Guys’ cover of Christina Perri’s “A Thousand Years“.
Do you listen to music while writing?
Thinking Outside the Books 
I generally don’t listen to music while writing, but I make an exception for Loreena McKennitt — I listened to her non-stop during my first NaNoWriMo. I’m particularly fond of her songs “The Never-Ending Road (Amhrán Duit)” and “The Lady of Shalott.” They’re peaceful songs, repetitive, and quite long — perfect writing music, in my opinion. If I need more energetic music to write a particular scene, I sometimes turn on a Two Steps from Hell playlist.
