Action function on a tilted upright

[reggaepass at aol.com]

David,

You WOULD have to ask, wouldn't you?  Why, indeed...

Because a composition student wants to do a Conlon Nancorrow-esque type 
piece for prepared piano.  We don't have any Disklavier grands here, 
just a couple of (ancient) MX100s.  From the sounds of it, I think his 
piece may exceed what a Disklavier is capable of in terms of speed of 
repetition and polyphony, anyway.

Cheers,

Alan E.

Alan:

I have zero first hand knowledge for you but I'd guess that you are 
right
about the action not working in anything but a vertical position.  In
addition, all the node points would be mostly behind the action (and who
knows how much Disklavier mechanism).  You certainly can't do much 
"playing"
inside the piano on a vertical.

I just have to ask, Why?

Hi List,

The issue is using a Disklavier upright as a prepared piano.  One is
limited in the selection of usable preparations by virtue of the fact
that gravity is working against them staying in place between the
strings (in a vertical piano).  Someone is entertaining the notion of
tilting the piano to horizontal (or as close to it as is workable)
while still having the action function.

So I'm just wondering if someone who has experience with this can save
me the trouble of finding out for myself.  My guess is that the action
will not work in the horizontal position, and will work increasingly
poorly the further from vertical it gets.

Anyone?
