Why does the spacing decrease going down the neck?

Since frequency is proportional to the length of the string, at constant tension, the string gets shorter by the reciprocal of that ratio. When you go to the next fret, you are starting with a shorter string, so the difference is smaller.

Are frets evenly spaced on a guitar?

But the frets are always perpendicular to the fretboard and the spacing between frets is always based on the overall scale. Technically a guitars scale is the distance between the nut and the center of the 12th fret doubled. The 12th fret is (for practical purposes) the midpoint between the nut and saddle.

Why are frets not evenly spaced?

Each time you move one fret away from the body, the pitch increases by a semitone. Therefore, the amount that the width must by shortened to increase the pitch a semitone gets smaller the higher you go in the range (i.e. the shorter the vibrating portion of the string is), and the space between frets get narrower.

Why do guitar frets get closer together?

When you stop the string with your finger, and pluck a note, you’re shortening the length of the string, which makes the frequency (and the pitch) go up. The wavelengths are spaced closer together as the frequencies become higher, so the frets have to be closer together to match the wavelengths you want to produce.

Should you loosen strings before tightening truss rod?

You only need to loosen your guitar strings before adjusting your truss rod if you want to tighten the truss rod. Tightening the truss rod creates extra tension on the strings, which can cause problems. If you want to loosen your truss rod, you don’t need to loosen your strings.

Does the spacing of frets on a guitar depend on string length?

On a typical guitar, the fret board has certain spacing between each fret. Does the spacing of frets on a guitar solely depend on the length of the string? Meaning if I have multiple guitars of different shapes and materials, but all of the guitars have the same length of string, will their fret spacing be identical?

Why does my guitar not play in tune on all frets?

Different guitars even by the same maker will often have different scale lengths from model to model and a corresponding adjustment must be made to the spacing between frets. If the spacing is not precise between frets, the guitar will not play in tune on all frets.

What is the 12th fret on a guitar?

The 12th fret is (for practical purposes) the midpoint between the nut and saddle. Therefore, the distance between the nut and 12th fret would mandate the location of the saddle and the fret spacing would be calculated based on the scale length using Pythagoras Ratios (a mathematical calculation).

What are frets made out of?

Anatomically, frets consist of a rounded “crown” (or “bead”) atop a thinner “tang” with barbs on either side as seen in cross-section. Individual frets are snipped to match the width of a guitar’s neck and hammered (lovingly tapped, more accurately) into slots pre-cut into the fingerboard.
