As already said above, with the max power supplied by an usb alone, you will never get even close to a spark. Nevertheless, if you meant controlled by usb (but powered by another source Ej. car batteries or a wall outlet), then it is feasible.
The USB protocol isnt my area of experience, but I imagine that implementing the midi function and the appropiate isolation between the Pc and the coil is complex. If you have never programmed any microcontroller before, or soldered, or read about tesla coils, I suggest you to make something simpler before attempting a musical tesla coil or ask for help to someone with experience in this area.
Anyways, if you are still insistent on making a Musical Tesla coil; start reading about solid state tesla coil. Even if they are not musical, solid state tesla coil can be adapted to play music, unlike spark gap tesla coil. I also recommend you to read about the ground requirements of a medium to large sized tesla coil, as maybe you havent taken it into account. Basicly, and medium and large tesla coil need a solid ground (not the house's one), consisting on several (depending on the size of the coil) bars jammed in the ground and connected to the secondary ground, which means running a tesla coil in a closed stage without a ground is unfeasable, dangerous, and wont give you good results.
If you have any question or doubt, please post. That's what forums are for.
