A pitch raise is a corrective procedure used when a piano is well below standard pitch (A440). Unlike a regular tuning, which fine-adjusts strings already near pitch, a pitch raise carefully brings the overall tension of the piano back up in stages.

What a pitch raise involves:
Gradually increasing string tension to avoid stressing the instrument
One or more preliminary passes to raise overall pitch
Pitch raises are common on pianos that have not been tuned for several years and are not a sign that something is wrong—they are simply part of responsible piano care. After a pitch raise, regular tuning helps maintain stability going forward.
