[CAUT] Re. More re. Unison Tuning

[Don]

Hi Jim,

I've always done my unisons aurally. The twenty minutes was a saving in
time over strip muting the entire instrument.

If I'm doing a pitch correction I rely on the ETD to compensate for
anticipated pitch drop.

If I'm doing an aural tuning (2 cents or less pitch correction on *any*
note on the instrument) I still do unisons as you go while setting the
temperament and of course, for the rest of the tuning as well. I do tune to
the open unison of the lower note when expanding out past the temperament
in this situation.

Jim's single string to single string approach means he misses an
opportunity to hear how the lower note is doing "unison wise", after it has
had time to "rest" a bit.

I've toyed with modifying the idea that Michael Gamble from the UK uses for
pitch correction wondering about how tuning might be if we "extended" each
note right from "square one" (i.e. tune a4, a3, a5, a2, a6, a1, a7, a0)
then proceed to the next note in the temperament. (f3,f4,f2,f5,f1,f6,f7)
All with "unisons as you go". It should slow me down I think!!!
