The DC Sunday jam has been happening almost every Sunday since around 1982. It has resumed after a period of COVID-19 quarantine and is happening weekly 

• Who: Anyone who is considerate and has a genuine interest in CI is welcome, regardless of prior experience.
• Where: See the event listing
• When:
  • On the first Sunday of every month we have an Underscore from 2 to 5 pm. We ask that those unfamiliar with the score attend the talk-through between 2:00 and 2:30, and everyone be present and ready to assemble at 2:20 pm.
  • On every Sunday except for the first Sunday of the month we start with an hour class and then have an open jam. The doors open at 2:00 pm and we often have a closing circle around 4:30 pm.
• Jam attendance costs $15 to $17, see the receptionist in the main building unless we are at an alternate venue.
• We maintain a note on our site's home page that always has the current status of the upcoming jams, so you can check there to see if there are any venue or schedule changes. (Such changes are rare.)
