[[Marvel]] is the 11-limit planar temperament tempering out 225/224 and 385/384. Marvel woo is the marvel tuning with 10/3, 7/2 and 11 as eigenmonzos. This gives three monzos with eigenvalue 1, and two with eigenvalue 0, allowing us to construct a projection matrix whose rows are fractional vals, which defines the tuning. This matrix is [<0 -4 4 4 4|, <-21 6 -6 15 8|, <7 -18 18 11 4|, <-28 -4 4 32 4|, <0 0 0 0 28|]/28. It leads to a tuning where the octave is sharp by |-7 -1 1 1 1>/7 = (385/384)^(1/7), about 0.643 cents. In this tuning, 9/5 is sharp by only |-49 -26 -2 19 12>/28 = (385/384)^(3/7)/(225/224)^(1/4), about 0.0018 cents. Putting 10/3, 7/2, 11 and 9/5 together with 2 leads to the full 11-limit. This means every interval in the 11-limit tonality diamond is either pure, ±0.0018 cents from pure, or a certain number of octaves away from an interval which is within 0.0018 cents of pure. Because of this, the beat ratios of everything in the 11-limit diamond are closely approximated by small integer ratios. For instance, for every eight beats of the octave in the chord 1-5/4-3/2-7/4-2, the approximate 5/4 beats approximately 20 times, 3/2 12 times, and 7/4 7 times; the actual numbers being 19.968, 11.977, 6.997 and 8 respectively. Aside from these facts about beats, it should be noted that marvel woo tuning is very close to the TE tuning for marvel. =14 notes= [[pum14marvwoo]] =15 notes= [[pummelmarvwoo]] [[dwarf15marvwoo]] [[dekanymarvwoo]] =16 notes= [[stellarhexwoo]] =17 notes= [[diam7plusmarvwoo]] [[dwarf17marvwoo]] =21 notes= [[dcon9marvwoo]] =24 notes= [[bimarveldenewoo]]
