    To drop the tuning a string by 4 semitones, you must decrease the tension to 63% of its original value.

    D'Addario lists the tensions of its strings (when tuned normally) on its site. Mind you, the tensions listed for normal long scale strings are for a 34" scale instrument, and the tensions listed for super long scale strings are for 36" scale.

    thanks alot! :D
    So if my E string is 40.3 lbs of tension, when i drop it to C, thats:
    63% of 40.3=25.389, so 40.3-25.389=14.911 lbs of tension.....

    That seems kinda low, are you sure its decreasing 63% of the original tension value or is it just 63% of the value?

    P.S. where did you get that information? thanks

    Tension is proportional to the square of the frequency. E1=41.203 Hz, C1=32.703 Hz (although you could take any pair of tones that are 4 semitones apart). (32.703/41.203)^2 = .62997 ≈ 63%.

    Which is a lot floppier.

    Consider that you're thinking of C tuning as a dropped E tuning. Very dropped. If you want to keep your tensions in a normal range, you should instead consider it to be a half-step raised B tuning, and buy a medium or light BEADG five string set, and use the bottom four and discard the G.
