An electronic musical instrument of a type capable of producing a musical tone corresponding to the tone pitch of a depressed key by controlling oscillation frequency of a voltage-controlled type oscillator by a pitch voltage corresponding to the tone pitch, wherein musical tone elements such as tone pitch and tone color are controlled in accordance with a control voltage which is produced for each individual key but is different from the pitch voltage. A temperature curve can be determined by controlling the tone pitch of the musical tone by this control voltage as well as by the pitch voltage. A desired temperament curve can be obtained by suitably adjusting the values of the control voltage for the respective keys. The tone color control is effected by varying the cut-off frequency of the voltage-controlled type filter in accordance with the aforementioned control voltage.
