Cleartune - Temperament Key Setting

Riley Hart · From: South Carolina, USA

Maybe a stupid question but;

I was using a custom C6 temperament in cleartune for my D10, and also a custom E9. No problems, they got me close, but now I seem to be having some problems deciding which temperaments to use on a U12 Bb6/Eb9.

I discovered a setting in the tuner that adjusts the 'temperament key', but never touched it before when i started to tune the E9 neck, only switched temperaments.

Is anyone able to shed any light on this?

For instance, if one tunes the E to 0 cents sharp or flat when it is referenced as the root, wud the 3rd need altered with different numbers depending on which note we are using for the roots?

BTW, when changing the key in Cleartune, it doesn't shift the current settings to different notes as far as I can tell...
Thanks, Riley.

I don't think it matters much in custom temperaments, but the various established ones, such as the various meantone temperaments, expect to flatten thirds and sharp fifths, so that if you choose the "4 comma meantone" in F, that will be different than the same meantone in A.
Since the custom temperaments involve departures from ET, I don't think key matters, but I ignore it just to make sure.

Makes sense to me I guess. Thanks Lane. I am trying to talk myself out of spending the money on a StroboPlus! Not that i can see how that would help, lther than combining different values for the same notes in a single preset.
I might visit my piano tuner friend today and enter his temperament octave settings and see how that works...

Okay. So i decided to move my tuning down to A6/D9(from my initial Bb6/Eb9 setup) to avoid the difficulties in transpositions and to get more useful open notes playing with my band, who is mostly in sharp keys. But my problem is more associated with coming up with a decent programmable temperament that will work with my tuning.

The default setup is standard C6 intervals and am raising my roots 1 half step to derive my E9 setup.

All the 12 string universal tuning charts begin with the E9 intervals open, and go from there.

So question may be, should I start tuning everything in the 6 tuning either ET or to a temperament which has worked for me previously on the back neck, and then attempt to temper the 9 tuning by adjusting the 1/2 tone raises to split the difference in the open sharped 5ths and flatted thirds?

Or does anyone know how to convert an e9/b6 chart to what i am using?

Or less specific, if any of you were dealing with this, what steps would you take to proceed?

I am getting more confused the more i think about it, and hope this question even makes sense!

Thanks for the suggestion Earnest. Might have been making this harder than it needs to be. My major source of confusion is that my guitar is tuned open to C6 intervals and e9/b6 is tuned open to e9 intervals.

Will try that next! Smile

Riley, I'd suggest tuning by ear or harmonics, and then, with your tuner set to ET, write down the deviation for each note, then program your tuner with those numbers.

Tks Lane! Got the blank chart sitting there waiting!
