piano action or hammer action is the mechanism that translates your finger pressing a key into a hammer strike on a string.
mechanism
- levers
- hammers
- springs
- dampers
key is pressed (lever lifts) -> hammer rises -> hammer strikes string(s) -> damper lifts off the strings
grand actions
grand actions sit horizontally (from below) and use gravity to reset the hammer.

upright actions
upright actions sit vertically and rely on springs to return the hammer to its resting position.
it uses a single escapement: key needs to rise further before the action resets
