Just Intonation Tuners Don't Match

Well, this can be a matter of both opinion and practicality and could be more complicated than your programable tuner will accomodate. There is also the question of note pitch variance with different fingerings.

Books on the subject;

Tuning and Temperament by J.Murray Barbour (ISBN 13: 978-0-486-43406-3)

Temperament by Stuart Isacoff (ISBN 978-0-571-23446-2)

How Equal Temperament ruined Harmony by Ross W.Duffin (ISBN 978-0-393-33420-3)

Personally I no longer refer to the tuning of the chanter as “Just Intonation”… it is closer to a Monochord tuning that I did discover noted down in the first of these books, but I don’t have the time at present to search through and point you to the exact page.

If you just want the ‘normal notes’ then you could start with these déviations from EQ;

D = 0, E +4, F# -14, G -2, A +2, B -16 ,C -29 and C# -10… of course , again this all dépends on fingerings and personal préférences.. prefer less diviation at F#, B and C… the C fingering giving harmonic flat seventh is fully forked… this allows one to obtain C# in a good place and to open the ‘forking fingering’ to get that Clancy sliding C coming through the EQ position.

Then there is all the sharps and flats to consider; is your F natural to be a flat seventh in the key of G or a perfect minor third to the Drone (D)… etc etc…

There are several other usefull fingerings that can be allowed for… just dépends what you wish to actually do with your Tuner.
