Abstract
An approach of a finger of a player to a key in order to conduct an operation for playing music is sensed to exert an external force which resists a depression of the key before the finger whose approach has been sensed touches the key. As a result, the touch feeling of keys of an acoustic piano perceived by a player right after depressions of the keys is realized.
