  1. That sounds right to me. Equal temperament sLsLsLsLs.

  2. I see. I had to look up MOS – “moment of symmetry”. I wasn’t familiar with the concept. Checking with a pocket calculator, I see that this uses a large step of 288.235 cents, a small step of 149.803 cents, and the scale pattern is LsLsLsLss.

  3. Hi b0b – there was an issue with Dimension Pro using the scala file as posted to tuning math. The first improvisation is lost to the ether… But the second improvisation I was able to salvage and it used this tuning.

  4. No they don’t map the same. The tuning by Scott Thompson is a 9-note MOS of BP diatonic with linear/isoharmonic 5:7:9

  5. Those numbers don’t map to the “traditional” diatonic BP scale, which may be why we’re hearing beats on some of the harmonies. See http://bp.b0b.com/2012/10/7-limit-harmonies/

  6. Hi b0b,

    It is supposed to the the tritave since it is following this tuning

    9-note MOS of BP diatonic with linear/isoharmonic 5:7:9, per Steve Martin | p = 3/1 (1901.955 c) | g = 438.038 c

  7. BTW, thank you very much for running this experiment! Could you add the scale documentation to this post, please?

  8. To me, that “clarinet” sounds much better because it doesn’t have the even-numbered harmonics of “strings”. I don’t understand what I’m seeing, though. What is the interval between the notes in the columns? Is it a tritave (3/1) or something less?
