Why: Since this oscillator is voltage-controlled, we need to change the voltage in order to watch the frequencies change. Changing the voltage on the power supply is not a good idea, because the op-amp needs a specific (and constant) power supply to function (we are only in possession of one variable DC voltage supplier) There are many different designs, depending on what kind of frequency range you need to cover. But all of them in some way will set the frequency based on some component that can be changed by a voltage. That could be a transistor, a diode, a vara..
