O Welt, ich muß dich lassen #4, 5, & 6

I’ve been working a lot with a spreadsheet to validate the tuning in cents, as opposed to just listening. Some of the keys just don’t comport well with the 31-limit tonality. While their “interestingness” is high, I think it’s important to hear what they sound like with a more or less historically accurate tuning. I found the last piece, in the key of F major was able to play almost all the just ratios I would have chosen if I didn’t restrict myself to the 16 note scales on the otonal and utonal that are available in 31-limit. But this chorale, “O Welt, ich muß dich lassen”, in the key of A major, just has too many 30-40 cent deviations from what just ratio I would prefer. So I redid the song using Carl Lumma’s VWRT temperament in A. It’s more conventional, and perhaps a lower interestingness, but here it is nonetheless. Three versions, since there is a lot of indeterminacy in the realization.
