A keyboard musical instrument includes an electromagnetic key touch generator for imparting a piano-like key touch to black/white keys, and the electromagnetic key touch generator has leaf spring members respectively held in contact with the upper surface of the black/white keys for urging the black/white keys toward the end positions and coil springs urging plungers of solenoid-operated key actuators to urge the black/white keys toward the rest positions; the resilient force of each leaf spring member is balanced with the resilient force of the associated coil spring at the rest position of the associated black/white key, and the solenoid-operated key actuator is expected to partially cancel the resilient force of the coil spring so as to build up resistance to the black/white key depressed by a player.
