According to one aspect of the invention, a turbine assembly includes an airfoil extending from a blade and a dovetail (300) located on a lower portion of the blade, wherein the dovetail (300) has a dovetail contact surface (317). The turbine assembly also includes a member with a slot configured to couple to the airfoil via the dovetail (300), the slot having a slot contact surface to contact the dovetail contact surface (317), wherein the dovetail contact surface (317) is reduced by a relief (302, 306, 310, 314) to alter a fundamental frequency of an assembly of the blade and member. A corresponding method of altering a fundamental frequency of a turbine assembly is also provided. |
