On Mondays and Wednesdays at 5 PM, Old Town School instructor Steve Levitt (whose bio on the site describes him as “Jerry Garcia meets Richard Feynman”) hosts How Do I Play That?, an hour-long “study hall” for guitarists. You don’t have to be a current student or even register in advance; just show up and find your way to room B7 on the lower level. 

Mondays at 6:45 PM instructor Charles Kim holds a similar open workshop for songwriters, each week with a different theme. February 25th’s is Creative Songwriting, Writer’s Block, Demos, and Arranging. It’s in the concert hall.
