Yamaha upright diskclavier on heavy tour?

[Isaac OLEG]

I would say you that the most problematic point for vertical
Disclaviers (I assume it is a vertical ?)is that the heat generated by
the alimentation inside the piano is very near the high basses, and
indeed having the piano plugged or unplugged change enough the
internal temperature to have the tuning moving too much in the full
middle of the keyboard (the worst place)

Servicing one of these, that is moved often, I finally find a medium
tuning that is not too bad when hot and not too off when cold, but
none of them is perfect. If the piano is used in a performance, I
insist to have it plugged all the time.

When you say you could correct the tuning yourself, if you ARE a tuner
it is of course possible, if you don't , correcting a few notes will
turn to be a much more difficult task than you believe.
Yamaha vertical pianos are very well suited for concerts and use in
moving events. They have a strong wooden structure that helps the
piano to bend when moved (not the smaller models). Despite of that,
you may be sure it is well seated on its four feet (grand pianos avoid
this problem because of their 3 feet)

But if you have a competent technician, and the piano remains plugged
all along, a tuning/week would be enough (1 hr work) - (consider
having 2 tunings the first week to stabilize the piano) After that,
only the temperature differences of the place, and the banging of the
pianist could untune the piano. If the piano is playing itself, it
hardly untunes because of that (not enough banging).

I believe your project is feasible and better than sampling, but it is
of course a matter of money ....

I've seen Disclaviers used in pieces, and they do the job very well.


Just a few ideas.

best Regards.

P.S. That's another story, but if your tuner is using a recently made
device to help him having better accuracy and eveness in tuning (I
mean a Verituner ) you should have a much more stable result, and the
tuner will have more informations on the way the piano moves. But I
understand you will be moving with the piano, then you should find a
concert tuner to stabilise the piano first to the point the tuning is
not to be corrected totally, only the unisssons - a concert tuner
knows how to settle the tuning so you can play Rock & roll on it.
Often a matter of experience, so you should ask expressely for that
objective (a tuning that can be banged) and may be envisage to pay a
little more for this part at first.

I work on rented pianos often, a very few tuners know how to settle a
vertical firm enough these days, they mostly work in rental concert
service, and explaining your wishes may be important (sorry if that
sound pretencious).
