In other words, RF's NST is another modified violin-based tuning: violin: G D A E NST:(C) G D A E (G) I think NST would have been perfect fifths if the string technology and instrument capabilities would have supported it. I think this is not dissimilar to the tuning of a viola-de-gamba, a fretted 6-string bowed viola-like instrument. Pat Hickey ***SPH brzrkr@nielsenmedia.com
