<DIV>Alan, you won't get any flames from me. My only complaint about the =
Yamaha
tuners is that I don't like the way they tune the bass, but you do that =
by ear,
so,,, I also play four octaves at a time =
up the
scale, listening for anything out of line. I think it's a great way to =
do a
quick check before heading out the door. </DIV>

<DIV><BR></DIV>Well, well .... uh, okay. This is really going to =
agitate the
sewage but ...<BR><BR>I don't "calculate" or "recalculate" anything. =
I'm using
the PT-1100 II<BR>(why? because that's what I have).<BR><BR>I will set =
the
temperament according to the best piano size match on =
the<BR>instrument. I
test the intervals (4:2 octaves, 4ths, 5ths, running 3rds =
and<BR>sixths). If I
don't find a pressing need to change anything (rarely do) I<BR>tune by =
the
lights down to the tenor break or first wound string and up to<BR>the =
top,
then unisons from top down to aforementioned break or
string<BR>change.<BR><BR>I tune down aurally from there, aiming for =
6:3
octaves (checking with ghost<BR>tones at the 12th/19th above my octave =
notes).
Should also hear approx. 1/2<BR>second rolls in double =
octaves.<BR><BR>After a
few notes, I run 10ths down starting at G35 or so and make =
sure<BR>there is a
smooth transition. If there isn't, I am more likely to pull in<BR>the =
octave
toward the 4:2 than to mess with temperament that I was
satisfied<BR>with.<BR><BR>Tune the bass, using the 12th/19th ghosts =
(very
accurate) and checking for<BR>pure sounding fifths (unless the strings =
are too
noisy with longitudinal<BR>inharmonicity--love them big words! =
Finally,
I run 17ths down and sometimes<BR>listen to double octaves.<BR><BR>My =
final
check is to play and sustain all the A's from bottom to =
top.<BR>Unisons
needing a touch up will stand out as will any questionable =
octaves<BR>(rare)
and you can hear how the whole tuning sounds in the piano. This, =
I<BR>then
repeat for A#, B ... to G#.<BR></BLOCKQUOTE></BODY></HTML>
