Here is how I compose text:
Over-the-ear headphones plugged into my computer, listening to a White Noise generating program. I used to listen to ambient music (and sometimes, I still do), but I often found that even instrumental music could be distracting. I use Scrivener as a word processor, with the full screen option on. After the session is finished, I turn on the Speak Aloud function to figure out the rhythms of the prose.
I am a digital ink-stained wretch.
