One way to read the table posted by Karl: In ET, the major third would be 400 cents (or 4 semitones) above the tonic (zero). But in JI, it is only 386 cents above the tonic; therefore, 14 cents flatter, or "offset" by -14 cents. A "compromise" tuning might flatten a major third only half that amount...

This is basically the same thing, except that it is built on a 12-hole format, and four useful chords occupy the last five chambers. All fo...

In this example, which is intended for play in the key of G major, the pattern is to have a Bb major ...

Brendan: Are notes in channels 1-3 repeated in 4-6?

Thanks, Alan. Could you please also share the dimensions? Would your next one be the same?

Wow, Karl! I will study your thoughtful response deeply!

Thank you so much!

The 5 draw note and is shared between two chords: as a p erfect fifth for one chord and as a root for the other chord. Therefore, it can be tuned to ET and will sound good for both chords. None of the major third notes are shared; they can be tuned to ET -14 cents. None of the septimal minor seventh...

This tuning presents no potential tuning conflicts due to notes being shared between overlapping chords. All of the root notes can be tuned to ET. All of the major third notes call all be tuned to ET -14 cents. All of the perfect fifth notes can be tuned to ET +2 cents. All of the septimal minor sev...
