I have a few favorites that seem to work best for me, which I have listed below, but I would be very interested to hear what others listen to, if anything, while they write.
Music for me helps set tone, but it also gives me a rhythm to work to. In my writing I try to create phrases and sentences and paragraphs that have a lyrical quality to them in that each world flows intuitively into the next for the reader in much the same way that a lyric flows into the next and then into the chorus and so on.
Anyway, my favorites:
Bill Evans (jazz pianist)
Dizzy Gillespie (his bop abd bebop tunes such as "Salt Peanuts")
Causes James Buchanan Supports
Expanding health care in the US, ending war as a viable tool of foreign policy, and issues related to social justice in general.
