I don't listen to music when I write, but I do turn on appropriate music when I read portions of my manuscripts back to myself - kind of like adding a soundtrack to help shape mood.
Erik LarsonTo me, writing is a very physical process. I lay out the entire book with the two narratives side by side on my bedroom floor, and just get down on my hands and knees and start looking at it in that physical space. "Does this really follow from this? Should this be here or elsewhere?" I will literally cut the paper into paragraphs. I'll cut it into segments and move the segments around from one narrative to the other until I feel that I've found the natural structure.
Erik LarsonBeneath the gore and smoke and loam, this book is about the evanescence of life, and why some men choose to fill their brief allotment of time engaging the impossible, others in the manufacture of sorrow. In the end it is a story of the ineluctable conflict between good and evil, daylight and darkness, the White City and the Black.
