A tunable mass damper assembly is attachable to a rotor blade (30). The tunable mass damper assembly comprises a base (52) configured to be attached to the rotor blade and a pendulum mass structure (60, 70) movably attached to the base and configured to move relative to the base in accordance with a rotational speed of the rotor blade about a rotor axis. The pendulum mass structure is configured to reduce vibratory forces of the rotor blade induced by a rotation of the rotor blade about the rotor axis. An entirety of the pendulum mass structure is configured to be contained within and enclosed by the rotor blade. Alternatively, the tunable mass damper assembly has a contoured shape in a direction between a leading edge and a trailing edge of the rotor blade. The mass structure may alternatively be positioned on a top portion of the blade, or along the leading or trailing edge of the blade.
