The JC ET part 1

[Richard Moody]

One demonstration is worth 1000 words.  I guess I don't understand how
F3 can be tuned 2bps flat when you are trying to find the correct rate
of A--C#.  It seems it is easier to recognise the A--C# beat rather
than guessing at F3--A3 being two beats flat.   A3 is tuned to the A4
and can't be changed.  A3 is to C#4  you want to know the right rate
here.  Sure you can set F3--A3 beat to be the same as C#4--F4  by
tuning both F's  flat, but how does that tell you have C# right?
Hopefully I will run into Jim at the convention and maybe he can
demonstrate.
    You say "| Yes but different pianos gives different beat speeds."
I say they are so close at least in performing pianos the difference
is not demonstrable or that the speeds are only a guide, not the final
word.   I say the quality of tuning is in the quality of 5ths and
"octave + 5 ths" and "double octave + 5ths".  These  count more than
the beat rates of  3rds.  If tuning F flat and then retuning it
correctly helps to get better 5ths then I am "all ears".    ---ric

| Hi Richard
|
| Yes but different pianos gives different beat speeds.
| I know it's possible to tune the F3-A3-C#4-F4 contigues to start
with
| but I found it easier to do what Jim Coleman taught me and tune the
A3-C#4 first with help of tuning those thirds equal beating with the
F3 and F4 2bps flat. after finding the A3-C#4 I tune the
F3-A3-C#4-F4-A4 contigues. Try it. It's fun. Please give me a response
on that.
