Piano Double Striking Fix | Omaha, NE & Lincoln Piano Repair

Press a key on your piano and instead of a single, clean note, you hear a rapid flutter or double hit. This is called double striking — a condition where the hammer bounces back and strikes the string more than once during a single keystroke. It is a regulation problem, and it can be corrected. Piano owners in Omaha, NE and the surrounding Metro Area — and also serving Lincoln, NE Area often encounter this issue in instruments that have gone several years without professional regulation.

Why Does Double Striking Happen?

Every piano hammer is designed to strike the string once and immediately rebound, held back by the repetition mechanism so it is ready for the next keystroke. When the action is not properly regulated, or when certain parts become worn, the hammer fails to reset correctly and rebounds into the string a second time.

Common causes include:

- Incorrect let-off regulation (the point at which the jack disengages)- Worn or sluggish repetition springs- Drop and repetition settings that are out of adjustment- Worn action parts that no longer hold their proper position

How Is Double Striking Corrected?

Fixing double striking requires a process called action regulation — a detailed adjustment of the many small components that control how each hammer moves. A technician will evaluate the let-off, drop, and repetition settings for the affected notes and make precise corrections to bring them back within specification.

In cases where parts are worn beyond adjustment, replacement components may be needed. Full action regulation is a skilled, time-intensive process, but it dramatically improves the feel and reliability of the keyboard.

Does Double Striking Affect All Pianos in Nebraska?

Double striking can occur in any piano — upright or grand — but it is more common in instruments that have gone many years without regulation. Nebraska's climate, with its wide humidity swings between seasons, accelerates wear on action components. Pianos in Omaha, NE and the surrounding Metro Area — and also serving Lincoln, NE Area should ideally be regulated every few years alongside regular tuning to keep the action performing correctly.

Frequently Asked Questions

What does double striking sound like?

Double striking produces a fluttering or bouncy sound on a single key press — almost like the note is being played twice in rapid succession. It is most noticeable when playing slowly or at low volume.

Is double striking the same as a repeating note?

They are similar but not the same. True double striking happens within a single key press. A repeating note issue usually involves the key or action not resetting between separate presses. Both are regulation problems a technician can address.

How long does action regulation take?

A full regulation of an upright piano typically takes several hours. Spot regulation of only the affected notes can often be completed during a standard service visit.

Yes. Legato Piano Services provides full and partial action regulation for upright and grand pianos throughout Omaha, NE and the surrounding Metro Area including Bellevue, Papillion, La Vista, Gretna, Elkhorn, Ralston, and Millard — and also serving Lincoln, NE.
