The third string goes through the body and resonates on a fretless neck seemingly identical to the second one. It can be ssen in the picture (bigger version.
I'm trying to imagine in what position a person must stand to play this thing. It must be rather unconfortable. Sitting down and playing it like an acoustic guitar is out of question, because your arm would damp the Y necks. Maybe as a slide guitar? I don't know. And I want to stop thinking about it. But I can't!
This seems awfully similar to an instrument that Hans Reichel designed and was using at least as early as the 80's (he had the cover feature and a SoundPage flexidisc in an issue of Guitar Player magazine).
Sure, the 3rd string is a new wrinkle, but having the string fretted and playable on both sides of the string was a major feature of Reichel's quite lovely 'guitar.'
Yes, this DOES seem very similar to some of Hans Reichel's instruments. This "y" shaped string is a significant difference, though, and seems to be much of what the Triare people are working on. I am very interested in the idea. I'll have to look at more of the research they have done on these multi-part strings.
For those of you who don't know his work, I HIGHLY recommend the music of Hans Reichel. He is an AMAZING inventor and makes music of stunning beauty. Personally, I prefer his guitar/stringed instrument work, but many feel his invention the Daxophone is even more interesting.
You might want to check out http://www.daxo.de/ It's an ODD site, and is a little confusing to get around on, but it's fun. A bit like a flash game...but educational about Hans and his inventions and his music. If I didn't already KNOW his guitars, I might find the site a little more baffling..... just go check it out. More importantly, check out his music.
I have created similar sounds by attatching a tiny lead ball at harmonic points on guitar strings. You can do it with bits of bluetack too, though it does not work quite as well as they fall off quite quick.
The problem is that it's hard to go much beyond open tunings or change key without everthing sounding like it's going through a ring mod. (Not that there's anything wrong with that :)
Listening to the tritare recordings they don't change key either, mostly soloing over a drone. I wish they didn't put that reverb+chorus+slapback echo on recordings.
