<DIV><FONT face=Arial size=2>The selection is somewhat a matter of
taste. The general pattern seems to be 6:3 in the bass to 4:2 in =
the
treble. I am experimenting with 8:1 octaves in both bass and treble, and =
find it
very sweet. I use Tunelab and don't know if Verituner has an 8:1 =
setting.

<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I have been using a verituner, and =
sometimes
struggle with octave widths. I am trying to use the partial list =
that
the machine gives me to determine the best octave widths. What =
are the
mathematical principles I need to calculate the widths. I have a =
list of
all 8 partials, how would I determine from those numbers what the =
width of a
2:1 octave would be if I tuned to the 4:2 numbers, or 6:3. =
Looking at
the numbers can I determine what the best stretch for any individual =
piano
from these numbers? I guess I am trying to get beat speeds from =
cents
measurements and understanding their relationship quickly before each
tuning.</FONT></DIV>
