-The '''just added sixth chord''' is a 5-prime-limit, 9-odd-limit chord of just intonation which is an "ASS", or [[anomalous saturated suspension]]. In close position, it is 12:15:18:20 (1⁄1–5⁄4–3⁄2–5⁄3), with steps 5⁄4, 6⁄5 and 10⁄9. Its inversion is 10:12:15:18 (1⁄1–6⁄5–3⁄2–9⁄5), in which form it can be called a just minor seventh chord.
