Fastening Faults
| A string can not vibrate freely all the way to its ends. The
string is fastened hard in both the nut and the bridge, much harder than we can press it
down with our soft finger tips. Also a string has stiffness. The stiffness obstructs the
vibrations close to the hard fastening in the ends. Consequently the vibrating part of the
string is shorter than the distance between the nut and the bridge. This fault is
corrected by increasing the distance between the nut and the bridge so that the vibrating
part of the string is positioned correctly above the fretboard. At the nut the fastening faults are eliminated by moving the release points away from the first fret. At the frets there are no fastening faults because our finger tips are soft. Neither a capo will cause noticeable fastening faults because its pad is pretty soft. At the bridge the fastening fault will vary, as the string is shortened when it's fretted. As the weight of the vibrating part of the string decreases when we fret the string up the neck, the fastening fault will increase at the bridge. But, as the impact of the bridge compensation also increases up the neck, we can realize that the fastening fault at the bridge can be perfectly compensated. |
