The Naval Cemetery Landscape — part of the Brooklyn Greenway Initiative’s efforts to connect the borough’s waterfront neighborhoods with a protected path and plenty of greenspace — has transformed a former hospital graveyard into a respite from city life. Visitors are always welcome to enjoy a soothing stroll around the gorgeous wildflower meadow, but the park is dialing up the relaxation this Thursday with its last sound bath of the season, led by musician and reiki master Teletextile. That looming morning meeting will feel eons away as you soak in an hour of singing bowls, gongs, vocals and other healing sounds. Be sure to register for the free class, which starts at 6:30 pm on the elevated boardwalk.
