Hi David, could you please tell me which gauges are you using? and vibrating string length, too. Maybe that could help to understand your issue. Regards.
2013/12/18 Sean Smith <[1][email protected]> Dear David, I'm kind of slow in the math department but in my experience low tensions strings _are_ more difficult to tune. When you get close to the breaking point - ok, and just a bit shy of almost there - they find that sweet spot rather nicely and you get a fine action around the tuning peg, too. eg, a quarter turn will yield fewer cents of change than at lower tension. That's just my experience. The higher tension around the peg also helps your control of turning so having pegs nicely fitted (and doped tho I almost never use it) will also help. That sweet spot/tension gives a better tone and I think more consistent. At lower than ideal tension the ring starts off higher and tapers lower according to my tricorder. Making sure your nut is well lubricated helps, too. Graphite is popular but I like beeswax for less mark up. The toughest time I ever had was a roped gut bass on a 4-course guitar that was short to begin with (~40cm) and then tuning it down a tone for one piece.

No, I do not want to use copper or silver wrapped strings. So, my question is if there is a relationship between the sensitivity of the frequency (pitch) to the tension of the string which would indicate that the tension on my string is a bit low. I did a chart of this in Mathematica taking the partial derivative of the frequency as a function of tension equation (assuming all else being equal) and it seems that frequency changes as 1 over the square root of the tension. This implies that increasing the tension would make the string be less sensitive to changes if frequency due to change in tension - i.e. easier to tune. Does this make sense to anyone or is it just noise? I am looking to see if changing the string will have an effect on tunability and whether it indicates a low or high tension change would be good. Thanks for listening to the ramblings and any guidance you can provide. These are expensive strings (Gut) so just experimenting is a bit spendy.
