Lead-safety Message: As the piano developed, the weight of the hammers increased in order to produce more volume. To keep the touch weight of the keys the same as it was in the instrument with light hammers, lead weights, were inserted into the piano keys which are placed in the front end of the key when the touch weight is too large and in the rear end of the key, if the touch weight is too small. There may be exposure when key leads are changed or piano keys are levelled using these weights.
