Harmony of Friendship is a group of six women (Tina Freidhof, Barb Yost, Karen Fisher, Terri Hopkins, Cindy Hoover, and Cinda Roteman) singing barbershop harmony.  In simple terms, barbershop harmony is vocal harmony sung without accompaniment (a cappella) produced by four parts: lead, tenor, baritone, and bass.

Everyone has friendship stories; stories that define what make each friendship so special or what makes a group of friends so fun to be around.  Two of the members of Harmony of Friendship (Barb Yost and Karen Fisher) are past members of the Greater Harrisburg Sweet Adeline’s and Sweet Adeline’s International.  It was Barb Yost’s vision in 2010 for this group of “friends” to sing barbershop at Saint Mark. The women have rehearsed tirelessly and worked very hard at learning the barbershop style.  They have developed a special friendship which is reflected in their caring and their singing--- “that’s what friends are for!”
