Jerry asks: >In tuning Major 4th's and 5th's pure, are the M3-M6 and M10-M6 checks >valid for checking that the interval is pure. That is, testing that >M3=M6 or M10=M6. Greetings, For pure fifths, the m3-M3 has proven to be a useful test. Going to the tenth is, imho, not as necessary for pure intervals as tempered ones. This may be just a personal preference. Actually, my personal pref. is the SAT! It makes these tunings, (and there are many), as easily provided as ET. Good luck, Ed Foote
