About Historical Fret Position Calculation: the Rule of 18
The historical technique for calculating the location for each fret is called the Rule of 18, and it involves successively dividing the scale length minus the distance from the nut to the previous fret by 18.
Beside this, are guitar frets the same size?
Actually, all frets have the same size. But they are positioned closer to each other as you go up the neck.
In respect to this, are shorter scale length guitars easier to play? All factors being equal (string gauge, string length beyond the nut and saddle, break angles, and so on), shorter scales produce lower string tension, are more elastic, easier to fret, and require less arm extension.
Secondly, does scale length affect fret size?
Fret spacing
As scale length increases, the distance between frets also increases. What is this? While you might not notice any difference between similar scale guitars, you would definitely notice it on a baritone guitar or a Fender Jaguar.
How do you measure fret spacing?
Divide any scale’s open string length by 17.817, and the result is the distance from the front edge of the nut to the first fret. For several centuries, this number was rounded to 18 and referred to as the “rule of 18.” For example, a typical guitar scale length (Fender Telecaster) is 25.5 inches (648 mm).
What is fret scale?
A guitar’s scale length is calculated by measuring the distance from the front edge of the nut, where it butts against the end of the fingerboard, to the center of the 12th (octave) fret, then doubling that measurement.
What is the advantage of a 12 fret guitar?
A 12-fret guitar has its bridge further from the soundhole, closer to the lower bout, allowing it to sit on a more flexible place on the top and offering more sustain on smaller bodies.
What is the difference between a 12 and 14 fret guitar?
A 12-fret neck is also slightly shorter than our 14-fret necks, with two fewer total frets (18 versus 20). The different positioning of the neck relative to the body shifts the bridge location away from the soundhole, closer to the center of the lower bout. This gives the guitar a distinctive musical personality.
What is the rule of 18?
The rule is sometimes called the “rule of 18”. Basically, the position of the next fret, is the scale length, minus the displacement of the previous fret, divided by 18. It was close enough, and is still pretty close. Although the accepted number today is 17.817.
What is the scale of a guitar?
Among acoustic guitars, the most common scales are clustered around 25.4–25.5 inches and 24.75 inches. However, to determine the scale of a guitar, you can’t just measure from nut to saddle, since the bridge saddle positions are moved or compensated away from the theoretical scale point to correct intonation.
Why do guitar frets get smaller?
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.
