The Medford Council on Aging is offering a free guitar class for beginners led by Chuck DeAngelis. The class will meet at 10:30 a.m. on Wednesdays at the Medford Senior Center for six sessions through October 25 (no class on October 4). Guitars will be provided, or you may bring your own if you choose. The class is limited to nine participants, and advance registration is a must. Call the Senior Center at 781-396-6010 to reserve your place.
