Hi List,   What's happening ?

Yes I replied to a message to Re:spinet octaves and I get this as an answer.
Am not sure I like a list moderator. In my moving I must have missed something that is happening.

The message says "suspicious header" Post files to files@ptg.org 
The header is in reply mode not a new subject. I assume that the objection is to the file but am not sure so I am not including a file with this message. If on the other-hand the moderator finds that the message is not appropriate, there should be a reason why.

On the 5/31 Farrell sent a message with a photo of a soundboard "soundboard #001" No file. So we now embed the photo or file into the text of the message to get across what we want to without having to post files separately. ?

So, the next question is, Who is going to moderate the list moderator ?

Hi Charles,

Sorry to be late with this reply, have been away working.

Tunelab uses a system to set the scale over the entire piano and this method
gives a very good tuning on the larger pianos but I have also noticed that
on spinets and other pianos that have high inharmonicity in the bass that
the bass inharmonicity constants (those things that set the scale when you
measure them) affect the tenor section to a greater than normal degree.

I also noted that the octave tests in the tenor section were, to me, too way
off to leave as they were so being an aural tuner I reset the scale and tune
aurally and use the Tunelab for the upper and lower sections only. (by
octave comparison)

I asked Robert Scott about this problem and he suggested that I try using
the 4:2 in the bass as this will narrow the tuning stretch down to make it
more acceptable in the spinets.

I tried this and yes it does work. A much cleaner tenor section.

>From earlier days, I remember a master tuner telling me that when you tune
the smaller pianos you tune to a higher harmonic in the bass than you use
normally. I was confused with what he was saying as in those days I new very
little about the harmonic structure of a string and a 6:3 or a 6:4 octave
meant nothing to me. I could understand that an octave should be pure,
unisons clean and fifths for some reason should almost be pure regardless
that logic says that they should double in discrepancy as they go up but
that is something else. Then I learnt about inharmonicity.

I have attached a my version of how I set up Tunelab for most common pianos
used in homes. This is the file of the Sample Mason & Hamlin that is in
Tunlab modified to show how I set it up.

1.    A0 is set on Partial 1 to show the actual fundamental.
2.    C6 is set on Partial 4 and C7 is set on Partial 2 to show (in the
tuning curve program) where the top note C8 should be and what the
variations in the treble scale are.

Measure C 1, 2, 3, 4, 5, 6. When measuring C1, if it is 50% more than C2 do
not use. Delete it.
In auto mode set the bass on 4:2 and treble on 2:1 and, press one of the
inner arrows to set scale.
Activate the manual mode and adjust all C's in the bass to as close as 0 in
the upper tuning curve as possible.
The treble will be close but you can see from the C6 and C7 markers on the
upper tuning curve where you can best set the last note.

This method may be a bit narrow for some of you but the tuning sounds (to
me) much better in the tenor and bass sections.

your comments would be appreciated as I also would like to make better
tunings easier too.

Regards

Tony Caught
