A tone signal source especially for electronic musical instruments having a plurality of output terminals for producing a nearly sawtooth wave output signal is composed of a plurality of frequency divider units each comprising a frequency divider circuit and a mixing circuit connected in such a manner that all of the frequency divider circuits included in the frequency dividing units are connected in cascade, and one of the input terminals of each mixing circuit is connected to an input terminal of the circuit or to the output terminal of the preceding mixing circuit, and the other input terminal thereof is connected to the output of the frequency divider circuit belonging to the output of the frequency divider circuit belonging to the same frequency dividing unit, so that a plurality of the output signals can be obtained from the output terminals of these mixing circuits.
