Analog frequency divider

This might not be the best way, please tell me if you have a better idea. I want to build 24 different oscillators one at each musical note ranging from 440 hz to 1661 hz ( 2 octaves ). My idea is to grab a 20k crystal oscillator and divide that to numbers close to the notes. Ex, 20k / 45 = 444.44 then tune that by a variable resistor or capacitor to reach the required frequency. I am ok with digital implementation, if all 24 oscillators can be on at the same time. I do not care what shape or form or amplitude the waves are at other than 50% duty cycles if it is a square, since all of that is going to be thrown at a PLL. please try your best to not make it drift by much. My timeline is 10 days from today. Please use realistic numbers for capacitors and such. One working circuit diagram for one of the oscillators is more than enough, if provided with good explanation.
