The culmination of years of work.Then the sooner we start, the sooner it'll be ready. What do you mean by "blocks"? Planar temperaments? I can see how it would be nice to have a dynamic version of Monz's diagram, where you could click on equal temeperaments or pairs of equal temperaments to get linear temperaments. But what you want seems to be the other way round -- starting with commas rather than equal temperaments. The problem with that is that it becomes multidimensional. Planar temperaments combine with equal temperaments to give linear temperaments, but planar temperaments combining with other planar temperaments won't work in general.>>> An alternative would be to name the important commas, and then >>> name blocks and temperaments by concatenating the names of the >>> commas involved, with prefixes to indicate vanishing. >>>> already there's the problem that the pythagorean comma doesn't vanish >> in pythagorean tuning. but i like the idea . . . nevertheless, what >> basis do you use? the TM basis for the 7-limit miracle kernel is >> {225:224, 1029:1024}, yet the breedsma does vanish too, which this >> wouldn't tell you by names alone . . . >> Good point. Maybe we need to name wedgies... does that solve the > problem?Wedgies or mappings will tell you if a given comma vanishes in a given temperament. You can start with a list of known commas and keep all those that vanish in each temperament -- no need to restrict yourself to the TM basis. What do you want them for? Graham
