→Finding unisons and octaves in a skip-fretting system: Note that some skip-fretting systems are better suited to live performance than others due to ease of maintaining tuning on the fly and why. |

For instance, for the standard Kite guitar tuning, `(edo, div, gap)` = `(41,2,13)`. Since `14 = (41 - 1*13)/2` is a whole number, there is an octave 1 string and 14 frets away. And since `1 = (41 - 3*13)/2` is another whole number, there is another octave 3 strings and 1 fret away. | For instance, for the standard Kite guitar tuning, `(edo, div, gap)` = `(41,2,13)`.

However, if the divisor of the system is coprime with the edo, alternating strings have no unisons or octaves. For example, 41edo has no divisors other than itself, so octaves can be found regardless of what interval the strings are tuned to or how many frets are skipped each time as long as the fretboard is wide enough. 46edo can be divided by two, so alternating strings on a 23edo guitar never have unisons or octaves, making systems like that harder to tune by ear or normal guitar tuners and use in live performance unless tuning to notes that they have in common with 12edo. | |||
