The root-major third-major ninth (approximating 4:5:9; J-L-K in Kentaku notation) and its minor equivalent root-minor third-major ninth (J-Lb-K in Kentaku notation) may be considered basic harmonic triads approximately like root-third-fifth chords in diatonic music; archeotonic scales have 6 such triads, 5 "major" and 1 "minor". The 11th and 13th harmonics are also plentiful, as already noted by Cryptic Ruse. | The root-major third-major ninth (approximating 4:5:9; J-L-K in Kentaku notation) and its minor equivalent root-minor third-major ninth (J-Lb-K in Kentaku notation) may be considered basic harmonic triads approximately like root-third-fifth chords in diatonic music; archeotonic scales have 6 such triads, 5 "major" and 1 "minor". The 11th and 13th harmonics are also plentiful, as already noted by Cryptic Ruse; 4 roots have the 11th harmonic over them and 4 roots have the 13th harmonic over them. The special chord 8:10:11:13 also makes its appearance, whose root can be said to be either on the "8" or on the "13", thanks to 13edo's conflation of 5/4 with 16/13. | ||
