 The modern equal-tempered tunings of the [[5L 2s|Diatonic]] scale can be similarly created using the [[12edo|12-EDO]] chord 2 - 4 - 5, with step sizes 2 - 2 - 1; this can also be extended to other tunings thereof, such as [[17edo|17-EDO]] (with the chord 3 - 6 - 7), [[19edo|19-EDO]] (with the chord 3 - 6 - 8), [[31edo|31-EDO]] (with the chord 5 - 10 - 13), and any other desired shade of the diatonic scale.
+== Maqamat and Ajnas ==
+The Arabic Maqamat are built using chords called Ajnas.  For instance, Maqam Rast is created using two copies of Jins Rast<!-- There are two forms of Jins Rast, often considered to be separate Ajnas; the difference between the two is the presence or absence of the Perfect Fifth. -->.  If we take an approximation of this Rast chord, such as the 9::12 tetrachord, we can use a Chord Interlace scale to create a reasonable approximation of Maqam Rast.  This can also be done for other Maqamat whose Jins are identical or nearly so, such as 'Ajam and Hijazkar.
+Keep in mind that while the generated scales might sound similar to the traditional maqamat, this method of approximation is extremely crude, and a very poor representation of the actual traditions.
 == Other Applications ==
-Chord Interlace scales can be used to approximate other musical traditions, such as the Arabic Ajnas and Maqamat.  If we interpret [https://maqamworld.com/en/jins/upper_rast.php Jins Rast] as a 9::12 tetrachord, for instance, then the Chord Interlace scale built from this tetrachord provides a convincing [https://maqamworld.com/en/maqam/rast.php Maqam Rast].
+Chord interlace scales can provide a useful structure for any JI or tempered scale.  Any and all chords can be used to generate such a scale - this includes [[Harmonic series segment|overtone segments]], undertone segments, [[generator]] patterns, [[Delta-rational chord|DR chords]], or any other arbitrarily-chosen chords the composer may want to use.
