Hi John and all. "... Treble... echoing round the rim..." is exactly how I would describe the sound on the floating treble pianos I crossed. Also, the amount and the aesthetic quality of the after ring is amazing on those (of course, partly because of the smaller dampers, but even with dampers lift, the reaction of the whole belly + strings to a single note in treble can be, well, magical or rather common). I suppose that this has to do with the fact that the energy input into the treble is not kept for long sustain, but more generously spent in the belly, leaving the sustain thing to the after ring things. Does this make sense ?

The treble on this piano is very special and gives the impression of echoing round the rim, but the my soundboard is not standard at all, so it's hard to say if this was a characteristic of the original. On Viennese Bösendorfer grands I have come across, the whole front edge of the soundboard is floating, heavily arched with a maple bar. JD
