major partials is obtained each striker 45 46 47 has associated therewith a solenoid which is switchably energized by supply 48 one terminal designated v 1 of supply 48 is connected in common to one side of each of the solenoids of strikers 45 46 47 for each bar of the set the other terminal of each of the 3 solenoids for each bar which terminals are designated as c 5 c 5 sharp d 5 etc and which are shown having an arrow connected thereto pointing away from the terminal are connected to the v 2 supply terminal through a switch which is closed when the corresponding key on the major minor keyboard is struck by the player the strikers 47 are positioned so that when they are activated the hammer associated therewith strikes the bar in order to provide a harp tone corresponding to the desired note the solenoid portions of strikers 47 are similarly activated when keys on the harp keyboard are played note that playing of a key on the major minor keyboard causes the striking of a corresponding bar with a pair of hammers 45 and 46 without the bar being struck by striker 47 although not shown in fig2 there is suitably associated with each octave of the major harp bars a variable resistor which is adjustable to fix the relative intensity of the pickup of the respective octaves the respective octave pickups being combined in series to produce the total major harp input at node 43 referring now to fig3 there is illustrated a set of bars 50 which are similar in arrangement and which correspond to the set 40 for each bar in set 40.
