How to convert my telsa coil circuit to allow for audio modulation? Answered

I am new to this but managed to piece together a working tesla coil. I used the steve ward sstc. The diagram can be found here: http://stevehv.4hv.org/SSTC5/miniSSTCfnlsch.JPG

How can I modify this circuit to allow for audio modulation?

It appears to be a DRSSTC circuit, using a 555. Replace the 555 with a microcontroller, and make sure to add some protection (clamping diodes and series pass resistors) between the microcontroller output and inputs of those amps to prevent damage to the microcontroller in case something goes horribly, horribly wrong. Then with the microcontroller, you can configure the digital outputs to ouptut different notes. I think there is a dedicated library in arduino to do just that.
