RE: Ultralight acoustic piano - Sorry to disappoint you, but the majority
of the weight in an acoustic piano does not come from the "furniture"
aspect. It is due to the heavy cast iron plate and corresponding structual
assembly required to support the combined string tension of approximately
20 tons of tension! Although modern metalurgy can produce an appropriate
structure, it is presently way out of line from a financial standpoint.
Although I rebuild, tune and prefer to play acoustic pianos, and use the
next best SUBSTITUTE, the electronic keyboard when I need portability.
Note: before you electronic fans start screaming replys to this, keep in
mind that there is NO electronic keyboard that can do what an acoustic
piano can do. They can digitize it, synthesize it, ALMOST sound like an
acoustic piano, but when being played, I have not found ANY electronic
piano that can reproduce the effect that can be gotten from an acoustic
piano, i.e. sound waves blending, amplifying each other, canceling each
other, etc. which can only be gotten from a vibrating membrane such as an
acoustic soundboard.

Has anyone tried to develop a piano that is 100% musical instrument and
0% piece of furniture? One that is so light it could be considered as
portable as a vibraphone? If one does not exist, would someone please
invent one? Why should pianists be in heavy bondage?

I second the above opinion. Along the lines of lightER pianos, I have seen
some small spinets that are very nearly portable. They have a shorter
keyboard (something like 5-1/2 octaves? - don't quote me on that), and are
double-strung instead of triple-strung. There's an excellent Seattle
busker by the name of Johnny Hahn who plays one of these on the street.
His is on wheels, and I'm not sure how he gets it in and out of his van,
but it's very portable and sounds very good.

I don't know if anyone makes these pianos any more, but I have seen a
number of them around.

Mozart had a portable piano about the size of a suitcase...he took it
with him on trips to use en route. The weight and size came with increased
tension (more volume at the expense of tone quality) and compass. Square
pianos were extremely popular until the turn
of the century...some small enough to rest on a table. Such acoustic
pianos are fine for personal/home use. For concerts you would have to
amplify them but at least you get the acoustic sound in a portable
package. You can pick up a good (antique) square at a bargain basement price.

Piano technicians tend to think that "good" and "square" do not belong
in the same sentence. :-)
If you see a good, square grand of the vintage and size of Mozart's
portable piano at a bargain basement price grab it. Most square
pianos one sees are easily 7' long and at least as heavy as a large
upright.

Another possibility if one of the "piano-fortes" now available. They
are generally light because they don't have the high tension, large
hammers, etc. Of course, they don't sound anything like a modern
piano either.

The bottom line is that there's very little about a modern piano that
is really furniture -- maybe not to 0%, but very small. Most of the
weight is in the iron frame, and wooden structure to support the frame
and keyboard.

This is true of the instruments that proliferated in 19th Century...they
were esp. popular in U.S. The European instruments are different animals.

The heavy 7' instruments are 6-7 octaves and have a full cast iron
frame...thus a `sideways upright'. Smaller squares without iron frame are
much more portable. I saw an 1820 Broadwood square, for instance, for
around $4,000 recently. So many of these were made there is no antique
value attached to them.

I make these fortepianos and the 5 octave ones can `easily' be moved by an

Actually, there are now some amazing hybrid keyboards now out. One somehow makes a large speaker into the soundboard.It's pretty weird. There are demonstration videos available online. I forget the maker, but it does signal a new wave of keyboard devices.

what about Klavin's Una Corda. I know it doesn't sound like a regular piano, but it's 100kg + you can remove the mechanism for extreme portability.

I was in a band in the early 70's that had a strung spinet that was light enough for 2 of us guys to get it into the van.
Can't remember the brand name but it was portable.
We carried it around to every gig.

Well, I did find this... It's a new-built square piano. https://www.jc-neupert.de/en/component/virtuemart/neue-instrumente/tafelklaviere/square-piano-mahr-detail

Just lose power and see who can still make music on their piano!!! :)
