    I find (for the most part -- there are always exceptions) that the only
ones that drop significantly after a pitch raise are pianos that  a) are
relatively new or recently restrung  b) were never stabilized at pitch when
they were new  c) were moved from another climate around the time of the
pitch raise.        --David Nereson, RPT, Denver
