Admitidly the bridge was of a = different type and in a different position than standard, however,=20 The tone was slightly hollow, the volume was down, but the sustain was = incredible. Ihave seen many old (1800s) piano with seemingly no crown = but still with a reasonably sound. I think the answer is quite simple. =20 Energy. A given amount of energy (caused by the vibrating string) will = produce both volume and sustain. If the volume is increased the sustain = is decreased and vice versa. It is still the same amount of energy = being used. The other factor is how much energy is lost by a soundboard being out of = balance, or too thick on the edges, or incorrectly mounted. Many pianists loved the sound of my experimental piano but to me, it had = the sound of another instrument. Something inbetween the sound of a = piano and a harpsicord. =20 Harpsicords have no ribs and no crown, possibly this is the tie in that = makes the piano sound like a piano.
