Chuck, you're confusing the concept of force with that of power. This is not semantic nit-picking, it's physics. I suggest that you do some reading of physics texts.
Here's a place to start: Force,wp.htm
Power is work per time.
In our case, the work is moving the string, the time is the cyclic motion. No motion in time, no power. It's really that simple.
