the 1979 analytical methods of John Barnes

- Practical "twang" instructions, explaining the basic concept here for people who are accustomed to thinking of temperament as beat-counting. Comma-splitting is listening for interval quality,
not numerical beats!

cent charts, comma splits, tone and semitone measurements, etc.

This tuning is installed in the
Opus 41 organ by Taylor & Boody
at the Goshen College Music Center, Goshen Indiana USA;
also in several others in Europe and the USA.

A digest of postings to HPSCHD-L
clarifying research details and answering questions
- New in November 2008! Jean-Philippe Rameau's published preference in 1726 was apparently for a system with regular 1/6 comma
tempering in Bb-F-C-G-D-A-E-B, and the other four notes tastefully arranged to fill the gap.
My presentation of this is in section 6 of the "practical instructions" page.
