Spring/summer 2006, the article "Bach's Art of Temperament"
further explains this temperament from several additional practical angles.
- January 2010, the published book review where I presented important theory about enharmonic scale assessment, and debunked
the 1979 analytical methods of John Barnes
- Other articles about this tuning
- A simple, informal speech introducing this tuning and the relevant issues around it
(i.e. a lecture inspired by the style of Richard Feynman)....
- Lecture slides from October 2008: explaining the tuning theory in an hour, with as little math as possible. This was a guest lecture at James Madison University (Virginia).
- Frequently asked questions (FAQ)
part 1, part 2, and part 3
- The background and process of the discovery
- 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!
- Practical instructions to set up Bach's tuning by ear, along with
other methods contemporary with it
- Electronic-tuner instructions [Main version]
A geometrical technique for quick tuning to set up any regular series
of consistent fifths: the core C-G-D-A-E and/or F-C-G-D-A for any temperaments (including Bach's) that have them
- Mathematical analysis of some of the musical results in this tuning's layout:
cent charts, comma splits, tone and semitone measurements, etc.

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.
