Jim,

If you are able to balance the pivotal thirds properly in step 5, then
your
mistake is happening in steps 6-9.  What aural checks are you using in
each
of these steps?

Corte Swearingen
Chicago


Jim,
 
Corte; Here is the progression with the tests I am using  
That's right Mike, I had step 11 reversed. It is straightened out below.
I am using tunelab pocket in a dell axim to check my aural temperament.
Something I have added are the beats per minute (bpm). 
I use bpm with my meteronome  as an aid to help compare the slower
beating 4ths and 5ths.
 
One of my faults may be expecting to master aural tuning in a short
time.
I noticed today that it was not always the E that was problematic
sometimes it was C# or G and G#.
Someone told me once that if piano tuning was easy, everyone could do
it.Thanks to everyone who replied. Have to go make some money tomorrow
(not tuning pianos) but hope to get back to my practicing on Friday.
  
1) A49 to fork          F33-fork = F33-A49   
2) A37 from A49         F33-A37< F33-A49  3rd is about .5bps slower than
10th  
 
3)F33 from A37   7bps              F33-A37<F33-A49 
 
4)F45 from F33                     C#29-F33< C#29-F45  
 
5)C#41 from F45 ...  balancing pivotal thirds
 
6)D42 from A37 (4th)1bps wide (60 bpm)        F33-D42 6th is 1bps faster
than F33-A37 3rd
 
7)A#38 from F45 (5th).6bps narrow (36bpm)         A#38-D42 is slightly
faster than A37-C#41
 
8)F#46 from C#41 (4th) 1.26 bps wide (80bpm)A37-F#46(6th) is 1.26 beats
faster than A37-C#41(3rd)  
D42-F#46 is faster than C#41-F46
 
9)C40 from F45 (4th)  approx 1-1/3 bps wide  (80bpm)     C40-A49 (6th)
is slower than F45-A49, its upper major 3rd  
C40-A49 is about the same asD42-F#46(M3)
 
10)E44 from A49 (4th) 1.6bps wide(96bpm)   C40-E44 is slower than
C#41-F45 and faster than A#38-D42     
A37-E44(5th) .6bps narrow    C40-E44  is slower than C40-A49 (6th)
this is where I encounter my problem?
 
11)G#48 from C#41(5th)less than 1bps narrow     compare E44-G#48 /
F45-A49(3rds) 
 compare C#41-G#48 / D42-A49 (parallel 5ths)
 
12)B39 from F#46 (5th) .83bps narrow (50bpm)  B39-D42(minor 3rd)is
faster than D42-F#46(major 3rd)   B39-E44(4th) is approx 1.1bps
 
13)D#43 from A#38 (4th) A37-F#46=B39-D#43
 
14)G47 fromD42
