Ghost Guitar Plays Hendrix

You could never make a self strumming guitar this way. The reason being that each open string has a fundamental frequency. As he demonstrated with his sweeps, the string will only ever resonate in a meaningful way at its fundamental frequency. In order to make the strings vibrate to a melody (beyond something that can be done with 6 notes on an open tuning), you will have to depress the string onto the frets. Moog actually released a guitar that does a very similar thing but uses the magnets in the pickups themselves to drive the strings. Fancy DSP would look for the loudest frequencies, amplify them, and then send them back out as magnetic field changes. The end result is that you could have an infinitely sustained guitar, or if you played with phase, selective string dampening (only one string can ring), and a palm mute effect (all strings dampened).
