When one speaks of the history of the piano action, mentioning the repetition mechanism (double escapement) invented by Sébastien Érard of France is a must. This mechanism allows the pianist to quickly repeat a note without having to fully release the key.

What is double escapement?
Double escapement occurs when the jack is reset beneath the hammer as the key is partially released. This allows the note to be repeated quickly without the action parts returning to their original at-rest positions.
When was the double escapement action invented?
Invented by Sébastien Erard in 1821.
What is the sounding mechanism of piano?
One end of the strings is supported on bridges, which are attached to the soundboard. The vibrations of the strings are transmitted to the soundboard through the bridges, and a loud sound resonates as a result of the soundboard vibrating the air. The entire piano, notably the soundboard, vibrates to produce sound.
Do I need escapement on digital piano?
If you learn on a digital piano without escapement, you'll experience problems when you sit at an acoustic instrument, unless you learn to play above the escapement.
