What if the artist does not like a particular aural tuning?  Jim C.

One can deal with the Artist's ideosyncracies in much the same way an
aural tuner does.  Find out what difference the Artist prefers and then
adjust the style of tuning to accommodate.  If they prefer a sharper
treble, one can increase the stretch numbers starting with the A4 number.
If they like sharper tuning in the top octave where many arpeggios reside,
one can increase the C6 stretch number. (There are other compensations
that are required here)   If one one wants more flattening
in the Bass, the F3 number can be increased.  If one wants only
certain notes tuned a certain way, those deviations can be added to the
standard tuning.  Violin players usually like the entire treble a good bit
sharper than standard tuning. No problem.  Jim C.

The thing that usually surprises aural tuners the most when they first get
the AccuTuner is how often the machine shows up their errors in their
aural tuning.  So the checking and rechecking works both ways, not just
one way.  One can be careless or sloppy in aural tuning just as one
can be in machine tuning.  When you check both ways, you have more
security.  The other thing an aural tuner discovers after beginning to use
a machine is that his "perfect tunings" are not the same each time.  This
tends to make one a little insecure at first.  How do I know?  And this
was after I had been a traveling Concert Technician.  Jim C.

In the previous paragraph one line reads: "if you know what's correct to
begin with . . ."  The problem here is that as a profession we have not
defined well what is correct.  It is often arbitrary.  With FAC tunings,
the general rule is that the double octaves are kept clean throughout the
scale.  Aural tuners probably deviate in both directions from this rule.
This does not make either method "the correct way."  We just do not have
any unanimity on this.  Steve Fairchild's Aural Tuning Emulator program
provides for any rule of stretch that a person could wish for and still
maintains consistency.  A certain amount of this kind of flexibility is
available in the new Reyburn Cyber Tuner which runs on a Macintosh compu-
ter.  If the REAL Concert Technicians can ever decide about the one
correct way to tune, it can be easily duplicated with a machine in the
hands of a skilled operator.   Jim C.

Thanks for listening.
