I'm still researching you know. For me this last year, what it's come down to finally after a lot of research, I realized that the harp orchestras in Egypt, six, seven thousand years ago, that they had all the harmonic knowledge then that we have now, just as far as what the monochord can do. And so I've just been devoting myself to the monochord and I realize that the trombone is really nothing more than an E string that's agitated with my lips and breath as opposed to clucking and bowing and all that, it's just different, but we're all working with the same wave. And the more that we respect the wave and the more that we know about the wave, the better chances of our getting inside the wave and becoming the wave and therefore controlling the wave. And this is our basic vehicle of communication, the wave.
