Action
The action of these small instruments is known as the "English single" and is unusually simple (for instance, it is far simpler than the original piano action as invented by Bartolomeo Cristofori.) It consists of a small "sticker" simply pushing up on a hammer, while a rod passing through the hitch pin plank lifted up a damper lever hinged from a rail attached to the spine. The action is illustrated below.
Action parts:
- key; the portion pressed by the player is on the far right
- jack; a wire with leather stud on top, known by the workmen as the "old man's head"
- whalebone rear guide, projects from the end of the key, works in a groove to keep the key steady
- hammer; strikes the string to produce sound
- whalebone jack, called the mopstick
- damper; when in lowered position stops the sound of the string
- whalebone damper spring

Famous quotes containing the word action:
“The Oriental philosophy approaches easily loftier themes than the modern aspires to; and no wonder if it sometimes prattle about them. It only assigns their due rank respectively to Action and Contemplation, or rather does full justice to the latter. Western philosophers have not conceived of the significance of Contemplation in their sense.”
—Henry David Thoreau (1817–1862)
“Rash actions are seldom committed in isolation. With the first rash action we always do too much. So we usually go on to commit a second one—and then we do too little.”
—Friedrich Nietzsche (1844–1900)
“Let the will embrace the highest ideals freely and with infinite strength, but let action first take hold of what lies closest.”
—Franz Grillparzer (1791–1872)
