A damping member (27) for positioning between the undersides of the platforms of adjacent turbine blades (20) and the peripheral surface of a disc (19) upon which the turbine blades (20) are mounted. The damping member (27) comprises first, second and third portions (28,31 and 32). The first portion (28) simultaneously engages the adjacent blade platforms (24) whereas the second and third portions (31,32) converge to engage each other at the disc (19) peripheral surface from a spaced apart relationship with each other at their attachment to the first portion (28). Frictional interaction between the second and third portions (31,32) and the disc (19) peripheral surface provides damping of turbine blade (20) vibration.
