Summary
Italy and the Iberian peninsula
Bartolomeo Cristofori (1655–1732) is generally credited with the invention of the piano in Florence at the end of the seventeenth century. Although some earlier accounts of keyboard actions survive, it is only from Cristofori that a continuous line of development can be drawn.
Cristofori entered the service of Prince Ferdinando de'Medici in 1688 as curator and instrument maker. In this capacity he maintained harpsichords, spinets and organs and made a variety of keyboard (and possibly stringed) instruments. His work on the piano may have begun as early as 1698, certainly by 1700, and in 1709 or 1710 Scipione Maffei noted that Cristofori had ‘made three so far, two sold in Florence, one to Cardinal Ottoboni’. In 1711 Maffei published a detailed description of Cristofori's pianos, including a diagram of the action (Fig. 1.1).
The action in Maffei's diagram works in the following way: as the key (C) is depressed one end of the intermediate lever (E) – which pivots around the pin (F) – is raised. This causes the escapement (G) to push the hammer (O) towards the string (A). The escapement then ‘escapes’ from contact with the hammer and allows it to fall back to its resting position, on a silk thread (P). When the key is released, the escapement, which is hinged and attached to a spring (L), slides back into its resting position and the damper (R) – which had been lowered when the key was depressed – comes back into contact with the string in order to damp the sound.
