Help hz ramping

00:28:41

My goal is to create a 5 second ramp up and down between 2 hz to 50 hz.  

Here is my attempt to create a ramping frequency, but I dont know how to adjust the circuit to meet my goal parameters.  

The NPN in the current design was an attempt to improve the draining of the cap, but I'm not sure if it is helping or hurting.

Help would be appreciated!
