Thread Name: Guitar string tension v gauge

Subject: RE: Guitar string tension v gague

The frequency is directly proportional to the tension, and inversely proportional to theweight.

The ratio in frequency going from C to E (4 semitones) is 1.05946^4 (1.05946 x 1.05946 x 1.05946 x 1.05946 = 1.2599), so for a given string, tuning from C up to E requires a tension at E 1.26 times whatever the tension was at C

Working backwards - tuning down, if you know the tension for the heavier string tuned to E, you can divide by 1.26 to get the tension for the same string at C.

Dividing by 1.26 is the same as multiplying by 0.7937, so you can estimate that the string tuned to C has about 80% of whatever tension it would take to tunethe same stringto E.

Clear????
