Associated Chamber Music Players (ACMP) Presented the Annual Virtual Worldwide Play-In 

Associated Chamber Music Players (ACMP)’s annual chamber music jamming weekend, the Worldwide Play-In Weekend, was held virtually this year on March 20 and 21, 2021. Each March, this grassroots event unites people of all ages and abilities through their common love of chamber music in honoring J.S. Bach during the month of his birth. Musicians around the globe joined in making joyous music together and people were invited to organize their own Play-In events on JamKazam, Jamulus, SonoBus, Zoom, or another virtual music session software of their choice. With repertoire ranging from J.S. Bach to Terry Riley, there were twenty-three events hosted in the U.S., Canada, and Japan: ten on JamKazam, six on Zoom, five on Jamulus, one on SonoBus and one on JackTrip. There were fourteen public sessions and nine private sessions sponsored by ACMP members and grantees. Before the eventful weekend, ACMP hosted three how-to webinars on low-latency music apps, which attracted 175 musicians. All events were free of charge.
