A complete technical reference for fretted instrument string tensions Catalog Supplement/String Tension Specifi cations RadioFans.CN 收音机爱 好者资料库 This brochure was created to assist in selecting the ideal string for your instrument and playing style. Included in this brochure are tension tables and formulas to help you calculate what tension a particular string will have on your instrument.

In order to determine the tension at which a string will vibrate, you need three pieces of information: the Unit Weight, the Scale Length, and the Frequency of the string. You can use the charts in this brochure to get a pre-calculated tension for the DAddario strings listed or you can use the formulas below to calculate the exact tension for any string using the scale length of your particular instrument. All of the charts illustrate string tensions for each string at a variety of pitches, in case you use alternative tunings. UW-Unit Weight. In all the charts and formulas in the brochure, unit weight is expressed in pounds per linear inch (lb/in). L-Scale Length. This is the vibrating length of the string. This is determined by measuring the distance from the nut to the bridge of the instrument in inches (in). F-Frequency or pitch. This is the pitch at which you will be tuning the string expressed in cycles per second (Hertz). On the following page are two fingerboard graphics detailing the various frequencies for the standard guitar and electric bass guitar. To calculate the tension of a string in pounds use the formula below, inserting the three variables described above: T (Tension) = (UW x (2 x L x F)2) / 386.4 To convert the result into Newtons, simply multiply by 4.45. If you know what tension you want the string to have, you can calculate the string unit weight. You can then use the charts in this guide to locate a string with approximately the same desired unit weight. UW (unit weight) = (T x 386.4) / (2 x L x F)2 A complete technical reference for fretted instrument string tensions 4 RadioFans.CN 收音机爱 好者资料库 e - 329.6 Hz b - 246.9 Hz g - 196.0 Hz d -146.8 Hz A - 110.0 Hz E - 82.4 Hz f - 349.2 Hz c - 261.6 Hz g# - 207.7 Hz d# - 155.6 Hz A# - 116.5 Hz F - 87.3 Hz f# - 370.0 Hz c# - 277.2 Hz a - 220.0 Hz e - 164.8 Hz B - 123.5 Hz F# - 92.5 Hz g - 392.0 Hz d - 293.7 Hz a# - 233.1 Hz f - 174.6 Hz c - 130.8 Hz G - 98.0 Hz g# - 415.3 Hz d# - 311.1 Hz b - 246.9 Hz f# - 185.0 Hz c# - 138.6 Hz G# - 103.8 Hz Nut / Open1st Fret2nd Fret3rd Fret4th Fret 1st String 2nd String 3rd String 4th String 5th String 6th String Guitar Fingerboard Layout G - 98.0 Hz D - 73.4 Hz A - 55.0 Hz E - 41.2 Hz B - 30.9 Hz c# - 138.6 Hz G# - 103.8 Hz D# - 77.8 Hz A# - 58.3 Hz F - 43.7 Hz C - 32.7 Hz d - 146.8 Hz A - 110.0 Hz E - 82.4 Hz B - 61.7 Hz F# - 46.3 Hz C# - 34.7 Hz d# - 155.6 Hz A# - 116.5 Hz F - 87.3 Hz C - 65.4 Hz G - 49.0 Hz D - 36.7 Hz e - 164.8 Hz B - 123.5 Hz F# - 92.5 Hz C# - 69.3 Hz G# - 51.9 Hz D# - 38.9 Hz Nut / Open1st Fret2nd Fret3rd Fret4th Fret 1st String 2nd String 3rd String 4th String 5th String 6th String Bass Guitar Fingerboard Layout (Standard Tuning) (Standard 6-String Tuning) c - 130.8 Hz Scale Lengths To calculate the exact tension for a string on your instrument, measure the scale length (nut to bridge) of your instrument and then use the formula on the previous page.
