| Chord information |
This chord can be modified by inflecting the 5/4 down by 25/24, the 7/4 down by 49/48, and the 11/4 down by 33/32 to get a 7-limit utonal minor counterpart 1–6/5–3/2–12/7–8/3, which is the inverse of 1–5/4–3/2–7/4–9/4. The chord's own inverse is 1–6/5–3/2–12/7–24/11. These four chords form a quadruplet in the 11-odd-limit, all being subsets of 1–5/4–3/2–7/4–9/4–11/4 and 1–6/5–3/2–12/7–24/11–8/3.
