You said: In a C to C octave the lower 5th interval C to G will be the =
same
beat rate as the higher 4th interval G to C.
=20
As I continue practicing my aural tuning skills I'm discovering all =
kinds of
"Aha!" relationships. The above relationship is one of them. Which leads =
me
to today's naive question: Is this also true when the 4th & 5th are
switched? IE: In the C to C octave described above, is the lower 4th
interval, (C to F), then also the same beat rate as the higher 5th =
interval,
(F to C)?

 PS Consider the following;
=20
"it would seem to me that there would be opportunity for higher partials =
to
be all over the place "
=20
That is the very reason why you should listen to them so that you CAN =
put
them in their place. They are very audible in the lower tenor and =
bearing
scale.
=20
"with the inharmonicity differences in wire. I.e., a plain wire and =
wound
wire. "
=20
Would this not be the very reason that manufacturers prefer the scale =
design
of low tension in the lower tenor to that of equalizing breaking strain  =
as
in Yamaha GH1?
=20
"I still don't see how you use that beat speed to put the wire being =
tuned
into your tuning pattern. "
=20
The second partial intersection of the 5ths would fall in to the same =
region
on the keyboard as the first partial intersection of the other main
intervals ; 3rds, 4ths and 6ths.
In a C to C octave the lower 5th interval C to G will be the same beat =
rate
as the higher 4th interval G to C.

AF,
Considering the spread of a fifth, it would seem to me that there would =
be
opportunity for higher partials to be all over the place with the
inharmonicity differences in wire. I.e., a plain wire and wound wire. By =
my
ears, the beats of the higher partials are no where near double =
sometimes,
but I haven't really got into it yet. I still don't see how you use that
beat speed to put the wire being tuned into your tuning pattern. More =
info,
please.

The beats are twice the speed so you can make a much more accurate =
judgment
as to the correctness of your interval.

AF,
And just exactly what would you discern from hearing the second, or =
higher
coincident partials? How would you make use of the information at that
point?
=20
Just curious.

>From Alan Barnyard's post: "5ths have such a slow beat that they are =
hard
for most to tune accurately, as a primary interval"
=20
It's much easier to use 5ths by listening to the second intersection of
partials and not the first. However you will have to sensitize your =
hearing
to discern that point.
