But that seems a long way from "teach a man to fish". The musicians will only be relying on the lists we give (and Graham's finder). ________________________________________________________________________ ________________________________________________________________________ ------------------------------------------------------------------------ Yahoo!

Extra-terrestrial music-makers (or humpback >whales) may find completely different regions attractive.This seems to be the key statement of this thread. I don't think this has been established. If it had, I'd be all for it. But it seems instead that whenever you cut out temperament T, somebody could come along and do something with T that would make you wish you hadn't have cut it. Therefore it seems logical to use something that allows a comparison of temperaments in any range (like logflat). Then no matter what T is, we can say... "You could have used U, which is in the same range but better." ...or... "T's the best in that range. Bravo!" ...The worst that could happen would seem to be... "T falls outside the range we established for our paper, sorry." ...in which case the reader could perform his own analysis in the above way. With a cooked acceptance region, however, the following could happen... "Oh, T. It didn't meet our guesses about human cognition, but YMMV." -Carl

What I don't understand is the resistance to moving on, and finding something that's approximately representative of human musical interest in these things. And if you mean it's a good function to modify to obtain the latter, then that's fine.

Can you elaborate?If |a b c d> is a 7-limit monzo, the symmetrical lattice norm (seminorm, if we are including 2) is sqrt(b^2 + c^2 + d^2 + bc + bd + cd), and this may be viewed as its complexity in terms of harmonic relationships of 7-limit chords. How many consonant intervalsteps at minimum are needed to get there is another and related measure.

And we're not suggesting any "goodness" measure which is applicable to both 5-limit and 7-limit systems of any respective dimensionalities. But we are suggesting something similar be used in each of the Pascal's triangle of cases, which seems logical. If it's wrong, it's wrong, and there goes the premise of our paper. But it's a theory paper, not an edict. I think if the criteria we use are easily grasped and well justified, we will have done a great job publishing something truly pioneering and valuable as fodder for experimentation.
