That > means that the single octave compass is based on that pure 3:1. Yep... and the rest of the piano upwards of the D3--A4 12th is tuned to a P 12th. as well. I was delighted to hear that Bernhard Stopper actually has documented a mathematical basis for this. Far more formal then my own musings and construction of a P 12th tuning with tunelab based on the 19th root of 3. Still, my own little inventiveness worked out great by my own ears... and when he told of his prior work on the matter I was pleased pink as it simply confirmed that what I had been fooling around with was indeed very supportable by applied tuning theory as well. Unfortunate that Stoppers work was not publised in the States when it first came out, and that tuners didnt start experiementing with it from the get go. Smart guy our Bernnie :) The bass tho, I tune with the best comprimise between 6:3 and 4:2 that I can get. I like a tight bass. > > Thus far you've been describing aural tuning steps, does this continue > for the temperament? If so, would that be a 4ths/5ths or a 3ds/6ths > temperament?

I prefer the latter as the 5th is so near to the heart of the 12th. >> I find it very easy to set D3(3) to an A440 fork using the 6th below >> test as an aid.

Yes... the same thing really... but doing both and comparing insures more accuracy... for me anyways. Cheers RicB
