The resulting system allows a player to reach any 13-limit interval by crossing a maximum of only 4 frets. Octaves lie across six open strings and one fret, or on the same string 18 frets up (because 90 is divisible by 18).&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot;&gt;&lt;/td&gt;&lt;td style=&quot;background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;One can play in 90-edo on an 18-edo guitar, by tuning the strings 17\90 (226 and 2/3 cents) apart.

&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;One can play in 90-edo on an 18-edo guitar, by tuning the strings 17\90 (226 and 2/3 cents) apart. The resulting system allows a player to reach any 13-limit interval by crossing a maximum of only 4 frets. Octaves lie across six open strings and one fret, or on the same string 18 frets up (because 90 is divisible by 18).&lt;br /&gt;
&lt;br /&gt;
The primes intervals lie in the following places:&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
!note&lt;br /&gt;
!fretboard position&lt;br /&gt;
|-&lt;br /&gt;
|0 steps = 1 % 1&lt;br /&gt;
|string 0 fret 0&lt;br /&gt;
|-&lt;br /&gt;
|90 steps = 2 % 1&lt;br /&gt;
|string 5 fret 1&lt;br /&gt;
|-&lt;br /&gt;
|53 steps = 3 % 2&lt;br /&gt;
|string 4 fret - 3&lt;br /&gt;
|-&lt;br /&gt;
|29 steps = 5 % 4&lt;br /&gt;
|string 2 fret - 1&lt;br /&gt;
|-&lt;br /&gt;
|73 steps = 7 % 4&lt;br /&gt;
|string 4 fret 1&lt;br /&gt;
|-&lt;br /&gt;
|41 steps = 11 % 8&lt;br /&gt;
|string 3 fret - 2&lt;br /&gt;
|-&lt;br /&gt;
|63 steps = 13 % 8&lt;br /&gt;
|string 4 fret - 1&lt;br /&gt;
|-&lt;br /&gt;
|8 steps = 17 % 16&lt;br /&gt;
|string - 1 fret 5&lt;br /&gt;
|-&lt;br /&gt;
|22 steps = 19 % 16&lt;br /&gt;
|string 1 fret 1&lt;br /&gt;
|-&lt;br /&gt;
|47 steps = 23 % 16&lt;br /&gt;
|string 1 fret 6&lt;br /&gt;
|-&lt;br /&gt;
|77 steps = 29 % 16&lt;br /&gt;
|string 1 fret 12&lt;br /&gt;
|-&lt;br /&gt;
|86 steps = 31 % 16&lt;br /&gt;
|string 3 fret 7&lt;br /&gt;
|}From these, the location of any compound interval can be added by vector-summing the string-fret positions of the interval&amp;#039;s factors. See [[Skip fretting system 48 2 13]] for details on how that&amp;#039;s done.&lt;/div&gt;</summary>
