This is a piano that is relatively recently strung and still shows some crown in the middle, maybe 1/16". Since I don't know how the bearing was set, what combinations of board/bearing settings might also contribute to this. I would be interested to hear what combinations generally produce what kinds of tone as a diagnostic tool. For example: A board with weak crown that has excessive bearing. A board with good crown but too light bearing. A board with weak crown and light bearing. A board with good crown and excessive bearing.
