A d-fret (3.5 fret) provides a note 9/8 from the nut. This can be very useful if using the alternating 3rds tuning (vM3 and ^m3) or an open tuning. For example in the alternating 3rds tuning, one can play a 5-limit downmajor scale by the nut with every other note as an open string, great for fast runs. An e-fret 7/6 from the nut provides 7-limit downminor notes. | |||
On a Kite guitar, each string fills in the missing notes on the neighboring strings. But there are 6 missing notes in the very upper and lower ranges. The 6 gaps in the upper range are fairly easily filled with half-fret bends. To fill the 6 low gaps, one might want short "[https://Fretlet.com fretlets]" on the lowest string, especially on a bass guitar. Their names run from a-fretlet to f-fretlet. | On a Kite guitar, each string fills in the missing notes on the neighboring strings. But there are 6 missing notes in the very upper and lower ranges.

There will need to be new 1/16" holes in the tie block. One could drill at an angle, entering from near the upper edge of the back of the tie block. But it's better to go straight in with an extra-long bit, perhaps 6" long. Or you can use a bit extension. This type is good because it's magnetic so there's no chuck to get in the way: [https://www.harborfreight.com/6-in-magnetic-hex-bit-extension-62691.html harborfreight.com/6-in-magnetic-hex-bit-extension-62691.html].

The nut will need to be replaced. Making a high-quality nut is a bit tricky for the amateur DIY-er, and you may need to use a luthier. But if the new fretboard has a zero fret, the nut merely serves as a spacer. It doesn't affect the sound, and the exact width and depth of the nut slots don't matter as much. Because both the nut and the tie block holes will be replaced, and because the new fretboard can be a little wider or narrower than the old one, one has a lot of control over the new string spacing. | The nut will need to be replaced.

In any given key, the Kite guitar has multiple "rainbow zones" on the neck. Assuming the tonic falls in the "sweet spot" between the 4th and 11th fret, it takes about 28 frets to provide 2 zones in every key, but it takes the full 41 frets to provide 3 zones. This 3rd zone increases the range the lead guitarist has to solo in by a 5th or so. The highest frets are very tight, but still playable melodically. Chording is very difficult. Having a 41st fret makes intonating the guitar easier, see [[How to make a Kite Guitar#Saddle%20and%20Nut%20Compensation|Saddle and Nut Compensation]] below. In general, if you can fit in 41 frets, do so. | In any given key, the Kite guitar has multiple "rainbow zones" on the neck.

There is a 'home zone" around the 14th fret that is the rainbow zone when the low open string is the tonic. There is a 2nd home zone around the 28th fret.

There is a 2nd home zone around the 28th fret. To get a complete 2nd home zone, one needs about 32 frets. Ideally this would be the minimum number of frets even on an acoustic or classical without a cutaway. Fortunately this translates to almost 19 conventional 12-equal frets, which almost all guitars have. | ||
The fret spacing is 1.71 times tighter than a 12-equal guitar. This chart compares it to the standard fret spacing. The spacing between the nut and the first fret is about the same as the space between the 12-equal 9th and 10th frets.

This section covers adding new frets or [https://Fretlet.com fretlets] (short frets that don't reach all the strings) to an already completed Kite guitar. The fret you are adding may or may not have a tang, and you may or may not need to cut a fret slot for it. A tangless fret is secured with glue or two-sided tape. You can place it temporarily with ordinary tape over the top of it, and check the cents with a tuner. Then mark the position with a pencil and attach it more permanently with superglue.

On an even-frets layout, dots (fretboard markers) are placed every 4 frets in a cycle of single-double-triple. So, the 4th fret has a single dot, the 8th fret has double dots, the 12th fret has triple dots, and then the 16th fret is back to single, and so on. Thus, a 36-fret guitar (pictured) has 18 dots on 9 frets, and a 41-fret guitar has 19 dots on 10 frets. | On an even-frets layout, dots (fretboard markers) are placed every 4 frets in a cycle of single-double-triple.

The small dots on the side of the neck follow the same single/double/triple pattern. The double and triple dots are oriented like the usual 12-equal double dots. At the 36th fret, the triple dots are too wide to fit between the frets.

Because the frets get closer as one goes up the neck, the double dots are closer to the triple dots than the single dots. As a result, if the distance between the double dots is the same as the distance between any two of the triple dots, the side of each "kite" formed by the dots is a concave line.

A 6-string Kite guitar tuned in 3rds can be strung with a standard set of strings, but it's not ideal. The high strings will be somewhat slack, and the low strings will be somewhat tight. To find the appropriate gauges, use the D'Addario method: calculate each string's tension from its unit weight, length and pitch (frequency) by the formula T = UW x (2 x L x F)<sup>2</sup> / 386.4. For open strings, the length is the guitar's scale. The frequency in hertz of the Nth string of 8 strings tuned in the standard downmajor 3rds with a low string of vD is 440 * (2 ^ (-7/12 + (21 - 13*N) / 41)). For a 6-string guitar in mid-6 tuning, N ranges from 2 to 7. Or use the [[How to make a Kite Guitar#Frequencies|frequency table]] below. The unit weight is pounds per inch, and is a function of string gauge and string type (plain vs. wound, etc.). <u>Unit weights for a given gauge vary by manufacturer</u>. One can work backwards from this and select string gauges/types that give uniform tensions. The formula is UW = (T x 386.4) / (2 x L x F)<sup>2</sup>. | A 6-string Kite guitar tuned in 3rds can be strung with a standard set of strings, but it's not ideal.

This is a standard (non-microtonal) luthier practice, search for "fretboard locator pins". With the fretboard clamped onto the neck, drill two (some suggest three or four) 1/16" guide holes through the fretboard and partway into the neck, to position the neck during glue-up. Drill the holes in the fret slots so that the frets will hide the holes. Drill off-center to avoid the truss rod. Drill one hole at the first fret slot and the other near the top of the neck. Do not drill into the body. Unclamp the fretboard and put 1/16" locating pins in the guide holes to position the fretboard exactly. If the fretboard wood is extremely oily (such as padauk wood), first treat it with acetone. Glue the fretboard on using ordinary [[wikipedia:Polyvinyl_acetate|woodworker's glue]]. Once the glue is dry, carefully remove the locator pins. Do one final levelling on the fretboard along each string path, then install the frets. | ||
