Step | Action |
1 | When key is depressed, the wippen rotates, moving the jack upwards while compressing the jack spring. The hammer starts to move. |
2 | The wippen’s left end actuates the damper lever, lifting the damper off the string. |
3 | The jack reaches its motion limit point when constrained by the letoff button. Thus, the jack disengages from the hammer. |
4 | The hammer continues to move by inertia and hits the string. |
5 | The hammer rebounds until it gets caught by the backcheck. |
6 | If the key is still depressed, the string is free to resonate. |
7 | When the key is fully released, the hammer falls back into its rest place, the jack returns to its rest position and the string is damped. |
