You are now on Massachusetts Avenue heading north. Follow Everett Street to the end. Go right at stop light. Find a place to park somewhere on Oxford Street and walk up to Paine Hall. Meters are in effect until 6pm, then they're free.
All metered spaces are free on Sundays.
As you walk up Oxford Street, the Peabody Museum is on your left. On your right is a large grassy area. Turn right into the driveway at the end of the grassy area. The Fanny Peabody Mason Music Building will be ahead, slightly to your left. Walk around to the back of the building to Paine Hall.
