The rooms of the Osborne Homestead Museum in Derby have been decorated to the theme of "Holidays at the Symphony" for the upcoming season. Members of the Olde Ripton Garden Club of Shelton are among those who helped prepare the museum for the holiday event. Each room will showcase the different musical components of the symphony orchestra. Upon entering the museum, visitors will see and learn about musical instruments and the Osborne family's influence in the music industry. Through Dec. 20, the museum will be open Thursday to Sunday, from 10 a.m.-4 p.m. The Friday hours are 4-6:30 p.m., when the museum will present "Twilight Tours" to highlight the glow of the decorations in the evening. Admission is free, and donations are accepted. In addition to the Olde Ripton Garden Club, volunteers for this event represent the Derby Garden Society, Garden Club of Orange, Long Hill Garden Club, Naugatuck Garden Club, Oxford Garden Club, Pomperaug Valley Garden Club of Woodbury, Roxbury\/Bridgewater Garden Club, Women Redefining Retirement and Ye Olde Kellogg Garden Club. The state-operated Osborne Homestead Museum is at 500 Hawthorne Ave., just off Route 34, in Derby. To register or for information, call 203-734-2513 or email firstname.lastname@example.org.
