Fact: While a crack in the soundboard can be a problem such as when the panel comes unglued from the ribs. Most soundboards have cracks within a few years after manufacture… you just don’t see them yet.

A single crack or gap is usually nothing to worry about, even several can pretty meaningless. If however you start getting more than 5 or 6 your soundboard is probably also losing its crown which will adversely affect the sustain and volume your piano will have.

The only pianos which don’t develop cracks in their soundboards are those with very flimsy frames which allow the soundboard to expand and contract without cracking and laminate soundboard (plywood).

A crack in the pin block is a much more serious matter. Now the piano will not stay in tune. Can you tell if there is a potential problem in the pin block?
