Abstract: An electronic musical instrument in which a keyboard circuit generates scale tone voltage signals corresponding to depressed keys of a keyboard. Plural musical tone signal forming sections are connected respectively to plural output terminals of the keyboard circuit which has plural series-connected resistance circuits. Each of the resistance circuits has series-connected resistances which, in turn, are connected at one end to an electrical source. Key-switches are provided to move with the keys of the keyboard, and these key-switches are connected so that when plural keys are simultaneously depressed according to a chord, respective scale tone voltage signals corresponding to the respective keys are generated at respective connecting points of the resistances in the series-connected resistance circuits, and they may be respectively transmitted from the plural output terminals.
