MessageJim,

Why not use your ETD to check each note after you've tuned it and find =
out where your having problems.

  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?

Jim, Corte; Here is the progression with the tests I am using =20
  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).=20
  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 =3D F33-A49  =20
  2) A37 from A49         F33-A37< F33-A49  3rd is about .5bps slower =
than 10th =20

  3)F33 from A37   7bps              F33-A37<F33-A49=20

  4)F45 from F33                     C#29-F33< C#29-F45 =20

  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) =20
  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 =20
  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    =20
  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)=20
   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=3DB39-D#43

  14)G47 fromD42
