Ralph you forgot to tune the F3. The F--A < F--D test being so ingenious (because F doesn't need to be tuned) (the F is also used to prove the A4--A3 with the source) I just had to improve on it. Why not make the F--A almost beatless (temporarly tuning the F ) Then the F--D rate is easily determined if it is beating faster. You would think, but it doesn't work, and the reason is (IMHO) why ET is so successful today. But for the G--B = F--D, the F has to be re-tuned to the D first. But that's hard to do because no matter where you tune the F, the F--A will always be slower than the F--D. . ---------- > From: ralph m martin <rmartin30@juno.com> > To: pianotech@ptg.org > Subject: Another tuning theme > Date: Thursday, March 19, 1998 4:55 PM > > The following is just another tuning theme..but with a rather novel twist > particularly for those with a knowledge of chords. > > Dominant 7th chord: 3rd and root beat the same as 5th and 7th in the > first and second inversion. > > Tune A4 as usual > Tune A3 to A4, beatless > Tune D4 a little less than one beat per sec to A3.
