7L 3s represents temperaments such as [[mohajira]]/[[mohaha]]/[[mohoho]], whose generators are around a neutral 3rd. Mohaha and mohoho form a [[Chromatic pairs|chromatic pair]] consisting of a [[Mohaha7|seven]] and [[Mohaha10|ten-note scale]]. | 7L 3s represents temperaments such as [[mohajira]]/[[mohaha]]/[[mohoho]], whose generators are around a neutral 3rd.

Additionally, due to the presence of fourth and fifth-like intervals, 7L 3s can be analyzed as a [[tetrachord|tetrachordal scale]]. Since the major 4-dicostep, the fourth-like interval, is reached using 4 steps rather than 3 (3 tones and 1 quartertone), Andrew Heathwaite offers an additional step ''A'', for ''augmented second'', to refer to the combination of two tones (''t''). Thus, the possible tetrachords can be built as a combination of a (large) tone and two (regular) tones (''T''-''t''-''t''), or an augmented step, small tone, and quartertone (''A''-''t''-''q''). | Additionally, due to the presence of fourth and fifth-like intervals, 7L 3s can be analyzed as a [[tetrachord|tetrachordal scale]].
