You are playing a 12th there Phil, and you are looking to make it perfect evidently. Play the F4 and the major 6th below it. (A flat 3). Listen to the fast beat rate that sixth will create. Now play that A flat 3 with your C6 and listen for the same thing... same coincident, same beatrate, same interval "colour" as it were. If you get a whole tenor treble section tuned exactly this way you will definatly get a bit of a different sound out of your tuning then if you stretch your tuning in another fashion. If you want to make 100 % sure you are doing perfect 12ths, your ETD can be used to confirm this. Just tune a notes fundemental frequency to the 3rd partial of the 12th below. Also... direct reference the 3rd partial, and use that to tune the fundemental for the note a 12th up. > > What I'm listening to is for the beating to go away..when that happens, > there is a gentle roll to the single octave(C5-C6), almost negligible. Correct.. and it will be just a tad wide, tho it will get wider and narrower in a slightly sporadic fashion due to the fact that you are forceing the pianos inharmonicity to conform to a perfect 3:1 12th priority. > Actually, I start this sequence as soon as I can, using the Temperament > Octave as a starting point..for me, the bottom of my temperament octave > would be F3 to hold and tune C5. > > I haven't changed anything in the bass..still 6:3 there. > > Aural Tuners - am I blowing smoke? Phil... this is exactly what that Tune lab example I sent out a few weeks backs does. You arent blowing smoke at all. Personally I think this illustrates one of the forgotten joys of ear tunings. Combining your ears, and your mind with the measuring and calculating power of the ETD can get really fun, and creative and educational as well. Cheers ! RicB -- Richard Brekne RPT, N.P.T.F.
