Do you have a certain kind of music that
helps you focus and write? What kind?
I rarely write to music intentionally. Most often, when I do, it's because there's background music playing at Starbucks while I'm writing. Sometimes will put on some soft ambient "chill" music or even jazz, or perhaps piano music that's not too bouncy. But honestly, what is best for me to write to is brown noise. That's right. Not white noise, but the more sedate brown noise.
And there's a wonderful noise mixer at www.simplynoise.com.
