The Musical Room Of Moving Resonance (jeez what a lame name)--

....anyway, imagine a large room with ceramic vessels of many varied sizes lining the walls. With a keyboard to make the initial tones, the sympathetic vibrations would occur only in the vessels whose size resonated with the certain pitchs -- thus, the sound would move about the room as the various sized vessels vibrated with their corresponding pitch.

Ever noticed the gargantuan radius of the average fiddle or doghouse bass and felt it would be almost impossible for you to learn to bow an instrument with so little leeway for error?   Then you are a candidate for the new RotofiddleTM. The four strings are arranged around a central rod and the bowing is done by rotating the whole instrument, rather than changing the angle of the bow.

If you have fears because you envision this new fangled fiddle boring its way into your shoulder/neck (getting screwed should be by show promoters -- not your instrument!), have no fear -- studies have shown that most musical compositions would require at least as much unscrewing as screwing.
