One way to play 63-edo on a 21-edo guitar is to tune each pair of adjacent strings 17\63 apart. That's about 323.8 cents, or 8.2 cents sharp of 6:5. | One way to play 63-edo on a 21-edo guitar is to tune each pair of adjacent strings 17\63 apart.

Among the possible skip fretting systems for 63-edo, the (63,3,21) system is especially convenient in that every 11-limit interval, and in fact every interval in the 2.3.5.7.11.17.29.31 subgroup, spans at most four frets. | Among the possible [[skip fretting]] systems for 63-edo, the (63,3,21) system is especially convenient in that every 11-limit interval, and in fact every interval in the 2.3.5.7.11.17.29.31 subgroup, spans at most four frets. | ||

From these, the location of any compound interval can be added by vector-summing the string-fret positions of the interval's factors. See [[Skip fretting system 48 2 13]] for details on how that's done. | From these, the location of any compound interval can be added by vector-summing the string-fret positions of the interval's factors.
