"With 3/2" denotes that the triads contain a [[3/2|3/2 perfect fifth]] of ~702 ¢. In these tables, the fifth will not be explicitly listed, due to the redundancy of listing "3/2" over and over. "Tertian-based" means that the second note generally counts as a third ([[Interval region|see Margo Schulter's interval regions]]). while "sus-based" denotes that the second note counts as a second or fourth, as in western [[wikipedia:Suspended_chord|sus triads]].
 
Of course, the boundaries between second, third, and fourth are "fuzzy" as described by [[Margo Schulter]], so subjectivity concerning interseptimal intervals such as [[13/10]] may arise. Editors are encouraged to add in their own viewpoints on this topic.{{Stub}}
