the irregularity is generated by an lfo (low frequency oscillator), sending a very low frequency (e.g. 3 hz) to the control input of the vco. let's assume that the lfo is already oscillating (generating) at 1,000 hz per second. by mixing a 3 hz low frequency with 1000 hz, as a result you get a "swinging" tone from the vco output, like e.g.
Repeat this setence, but with the correct capitalization.
