[pianotech] Aural Tuning, a third flat

[David Love]

The beat rates would be slower.  But why not just pull it beyond pitch by a
factor of 25% (30% in the treble) so it falls back about where it should be
by the time you're done?  Afraid of strings breaking?  If they're going to
break, they'll break anyway.  First pass to get it close, second pass if you
missed your mark doing it aurally, third pass to fine tune (charge
accordingly) and then come back in 3-4 months to tune it again (though it
will likely be 3 years if they let it go this long the last time).  I don't
believe in creeping up on the pitch.  Just get it there, do your best to
fine tune it on the second pass and schedule the next appointment sooner
than the last one.  This is where an ETD comes in handy for accurate and
fast pitch raises so the fine tuning has less distance to travel.

Dear Friends,

We have been told that the beat rate for A3-C#4 is about 9 bps; F3-A3 is
about 7 bps; do these beat rates only apply when A4 is close to 440?  

If A3 on a neglected piano is closer to F#, are those beat rates the same?

I recently tuned the most out-of-tune Acrosonic I've ever seen in 22 years
of tuning.  I did my best and the piano sounds better than I'm sure it's
sounded in years, but I didn't dare get the A anywhere near my 435 fork. I
decided just to raise A4 a bit and tune it from that point.  Of course, if
it slipped, it would throw everything off, but I had no other reference
point.  I will tune it again in a few months.

Can I use those traditional beat rates when the A is somewhere around 420?
Just wondering...
