Pythagorean tuning is the basis of "cajun" tuning

See link.

For the record.. Savoy does not use the common "Cajun" tuning ... he neither flats nor sharps to the degree that others do, and I believe not all the normally retuned from 12TET as the reeds are supplied from the reed makers.

I have checked some of his boxes and spoken with him about this.

I believe the real reason is time saving and appeals to more than "Cajun" ears.

Some folks also call Cajun tuning "just" tuning.. bet there are mkore than one "just" tuning. Hohner Marine Bands and Blues Harps are "just" tuned.. as are Spcial 20's but I think modified a bit..Golden Melodies are 12TET.

If the Pythagoreum method had been presented to Sidney Brown, I'm guessing that he might have excused himself from the conversation. Given all the variables that affect tuning, a few cents this way or that may play in the lab, but not on the stage.

Iry Lejeune didn't fret too much about tuning, he just played the music, and delighted his audiences. Talent and style trump precision en la poussière.

The early Cajun builders including Brown copied German box tuning.

It is not necessary to know anything about something if you copy.

The more I learn about tuning, in it's broad sense, not just cents, the more confused I get.
