Repetition Spring Regulation
By Larry Lobel
Regarding repetition spring regulation on grand pianos, I use the standard given in a Yamaha service manual:
"There should be enough tension to raise the hammer to the point where
the repetition lever touches the drop screw. If the hammer rises so
fast as to create a "bump" that can be felt in the key, too much
tension is present."
While you can't always achieve this standard on older pianos, it is a good ideal to strive for. It makes sense because the pianist wouldn't want to feel the "bump", but you want that lever to rise as fast and as far as possible for the quickest response to a repeat keystroke.
