And do so with the least extra notes anad keys above 12. I found 19 noes to the octave would do this when slightly tempered. Some of the results were free extras. Such as being to play in C major, 7c minor and tertian e minor with the same tuning. And having several secondary scales related to these with the same tuning. Pauline

How were they > relevatory? I adjusted the Phillips scale to the 7-limit consonant intervals in included with a margin of 5 cents, and then of 2.5 cents, and it showed the errors needn't be as great, and suggested how the 5-limit substructure looked.
