One of my pet theories as to why mankind is so messed up is because people stopped playing music together. I’m not talking about musicians — I’m talking about regular people. Somewhere along the line, the ritual of music, the act of people gathering to play or sing together for no reason other than to do it, got lost. Music became a commodity instead of the community bonding experience it was meant to be. Stephanie Auld is trying to change that. With the holiday season upon us, the trained soprano has organized a Christmas sing-a-long at the Covenant Woods Retirement Community with an open invitation to anyone with the time, will or inclination to join in. Some might think of this as an act of charity, but it’s more than that. It’s an opportunity to experience music as it was meant to be experienced: as an active participant. The Christmas Sing-a-long is Friday, Dec. 13, at Covenant Woods, from 1:30-2 p.m. If you’re interested in singing with the group, email Auld at email@example.com.
