I know about the old Schumanns,
They have a decal that says "Built like a Violin" which I never
could quite understand. The ribs structure is a radial design where
they all originate at one end of the board near each other and then
radiate away from each other. The idea was to space ribs in an infinite
variety ways so that every harmonic would be allowed to vibrate. The
tone seemed typical of lower end american grands from that era, and the
piano was lightly built and boasted about having a "low tension scale".
There were only three sections and no agraffs. Such pianos can be made
to play quite well and often can have responsive actions and functional
but they are not class one pianos.
