approximation to just intonation
So each row was tuned to just intonation based on the tonic note in that diatonic scale? Presumably 5 limit?
Yes that would give issues cross rowing, definitely on a semi tone box, need to think a bit how bad on a fouth appart box.
Now on an instrument that only plays in one key, I can understand just intonation, but why on earth not do twelve equal tones on an instrument designed for different keys is beyond me ...
Edit: Just worked out what happens on a fouth appart DG box when tuned with 5 limit just intonation. There is only one duff note when cross rowing, and that is the E; the E on the D and G row are in an 81/80 resonace, that would sound grim .... If my maths is right that is almost a 22 cents difference ...
