ABSTRACT OF THE DISCLOSURE There is described a musical instrument such as a piano comprising a plurality of vibratile members such as wires capable of vibration to produce notes of selected frequencies, a hammer mechanism for each said vibratile member for causing vibration thereof, and an actuating mechanism for selectively rotating each hammer from a rest position to strike the vibratile member associated therewith and a return mechanism for rotating the hammer back to its rest position. A hammer rail is provided to support the hammer in a rest position. A control mechanism for the hammer includes a pivotally mounted adaptor having an inertial mass movable in a substantially vertically upwards direction and active upon the hammer when struck thereby to absorb the kinetic energy of the hammer moving towards the hammer rail to thereby exert a decelerative force upon the hammer. The hammer rail has a surface of resiliently deformable material such as felt which the hammer abuts in the rest position thereof. The pivotally mounted adaptor is located for striking by the hammer moving towards the hammer rail substantially at the moment of initial contact of the hammer with the felt.
