Beat frequencies?
That's what I'm thinking. Just getting the beats so fast that they sound like a tone.
here's the email I sent to her:
I have just stumbled upon your wikipedia page, and am curious; could your subharmonic technique be applied to guitar, specifically electric guitar?
Yes, I know, it's probably the least respected instrument (yet most outrageously popular, ironically) there is, but aside from piano - and not going all john cage on my baby grand - it's the only one I can play.
Is your technique dependent on the position of the bow relative to the string? I would assume it would be, as it seems you're creating very fast 'beats' - so fast they would be perceived as musical notes, if that makes any sense. You say that the subharmonics like 'twisted strings;' I assume that this means wound strings, correct? Have you ever tried this pizzicato, or is that not possible? Have musicians of any other instruments besides violin asked you about this?
If this is not possible with a plectrum, I will probably try this with an E-Bow, But the attack on that is very slow. Is a hard attack absolutely necessary?
I think I have somewhat of a grasp on how this is done, although I will have to dig out my copy of On the Sensation of Tone to re-read and get my head around this.
