I've always heard that Draw 5 for 7-lim Just
intonation is tuned -27/-29 cents relative to 12-TET.
When I research Just Intonation independant of the
harmonica all the charts show a minor 7th scale degree
at +18 cents. What up?
It looks like you have everything at ET except the 5 draw at -29 for that.
You can play around with the tunings with the spreadsheet at http://trinity.psnw.com/~dlmurray/data/Tuning.xls to see what effect
changing one read has on the other intervals. It changes stuff all over the
place.
