[pianotech] Aurally pure octaves

I am intrigued with this thread, especially the way Ed hears partials. I
just hear beats and use them to complete my goal.

I have enjoyed the discussion on the tuning methods of Virgil Smith. I met
Virgil in New Zealand in 1998 and attended a three hour lecture on his view
of tuning. Over the last couple of days, I have re read his lecture notes
and read his book. many times.

As per usual with piano technicians, Virgil's lecture was viewed as both
good and bad. I kept my opinions to myself, wanting to try them out for
myself. The idea of not using a temperament strip was not new to me as a
couple of tuners I knew believed that temperament strips were for amateurs.
Other techs believed that you could achieve better accuracy with a
temperament strip in the mid section. They  also added that it was faster
with a strip. We all have strong opinions.

I came up with a solution that I would tune a F3-F4 temperament with a strip
and then tune the unisons, and finish off the piano using "open strings". I
found that I was using 98% of Virgil's instructions, and it is so close to
the Yamaha method mentioned in the past weeks. I have to add that some
technicians agree with the 10th being faster than the 3rd with the same
bottom note, like Virgil (example) and some disagree. The saga continues.

A technician I spent a lot of time with tuned using 3rds & 6ths temperament
with one felt wedge, and he told me that there was only one good method in
tuning. His.. His tuning is so similar to Virgil's except for using the F3
F4 temperament. He told me that if I wanted to become a better tuner, I
should adopt his methods.. Boy if I had a dollar (USD) for every time I have
heard this..

I did try his method but found the single strings a little difficult..
Mainly because I could tune faster with the 13 notes in the strip.. And
believing that I could be more accurate with the strip.

Thanks to this thread and the comments by Ed, Kent and David, I decided to
give the single strings a go. I have tuned one of my concert instruments
every day this week, and yesterday I decided to use the VS method. I still
used the F3 F4 temperament with 3rds & 6ths, however I then worked down to
D3 just to follow Virgil's method. I found that my tuning followed Virgil's
rules, but the interesting thing is that although the tuning was almost the
same as the previous strip method. the new sounded better. why???  Is it
perception ??

Today I had to tune the piano twice.. one for concerto rehearsal and tonight
for concert and with recording for radio. Today, I didn't listen to 4ths
after F4, I just tuned the octaves and checked with progression of 10ths,
17ths etc etc. And the piano sounded great.. I am not really one to sing my
own praises (Un Australian) however the piano did sound great.

David Anderson, you are the most vocal on this list for this method, so WHY
IS IT SO ?....... (BTW I hate to tell you that my 4ths still are increasing
in speed.. but not much.  SORRY)    However it is something not to loose
sleep over. or to spill my nice red wine I am currently enjoying.. It's
Friday night!

To finish, it is interesting to read how other technicians use different
methods to achieve the same result. Either strip muting the whole piano then
tuning unisons to finish or listening to specific partials. It proves how
wonderful the human brain truly is. We all use our individual method, which
is using the methods which were passed on to us..some good, some bad..    

I just remembered something about the perfect 12th. I know that it has
nothing to do with Bernard's software, however I attended a Yamaha lecture
in November 1984 conducted by Yogi Suzuki from Yamaha. (I was 4 weeks into
my apprenticeship) and he told us about using the 12 and 19th in tuning. The
idea really rocked the tuners who attended. Most tuners disagreed with his
idea as they thought the octaves were tuned too sharp. Three years later I
asked Wayne Stuart at Preston College and he said that it was an ok plan
however the interval was too broad and it was better to refine the tuning by
using the 10th or 17th. What do others think.. David ????

As we say this side of the Pacific... Havagoodweekend..

William-

 

Since I can do both, I'll explain:

 

When I listen "musically" to a Major third, say F3-A3, the beating sounds
like its a vibrato happening at the pitch level of the thirds; imagine, say,
a violin playing the third with vibrato.

 

When I listen "analytically," I let my hearing scan up the overtones until I
hear the co-incident partials where the beating is occurring. Now I can
recognize that the beating that I first heard at the fundamental level is
really happening at the 5/4 level and that there is no beat at the
fundamental level.

 

As long as I can remember I have been able to listen to a tone and
consciously isolate many of the partials of the tone. I thought everyone
could do this, but in teaching I've learned that not everyone can. I've also
seen people who could not hear the partials of a tone suddenly become able
to hear them.

 

When I talk of different modes of perception, I am referring to these two
different ways of hearing which I can usually effect at will by just
imagining how I want to hear.

SNIP 

 

I was drawn to the idea that tuners need not listen to beats at their
specific pitch levels, since I am one the tuners who has never heard
coincident partials at a their actual pitches.

 

Whole sound tuning is where it's at. It is not secret knowledge. I'll be
attempting to demonstrate next week at the Central-West Regional Seminar in
Wichita.

Kent,

Can you explain this more clearly?  I know it's been (re)hashed many times
and, recently, but, where DO you hear the coincident partials if not at
their specific pitches?  I'm more than open to learning/experiencing this
technique, and I've no doubt standing behind you (Virgil, DA, etc.) would be
far more instructive, and I intend to do that at GR if DA gets it going; but
for now, are you just listening to "everything presented" at once?  Or is it
something different, specific to partials, but with a slightly different
focus?
