Visit NSAI (Nashville Songwriters Association International) If you are a member, stop by to say hello, book a writing room, schedule a mentoring session for while you’re in town, learn about the industry in the well-stocked resource room, use the computers or just hang out in the lounge. If you’re not a member, drop by to find out why you should be. The staff is friendly and supportive and it’s their job to help songwriters. Plus, a major goal of any trip to Nashville should be to meet people, and if you go to the NSAI office it will be filled with songwriters who want to meet other songwriters.
NSAI Thursday night workshops Every Thursday from 6 to 9 pm there is a workshop at the NSAI office (1710 Roy Acuff Place, 37203) designed to help you learn about the music business and become a better songwriter. Some weeks feature song critiques by pro writers, sometimes there’s a speaker from the industry and once a month there is a “pitch to publisher” night. There is no charge for NSAI members. If you are not a member you can go to one or two before joining.
