The earliest known keyboard instrument was the Ancient Greek hydraulis, a type of pipe organ invented in the third century BC. [2] The keys were likely balanced and could be played with a light touch, as is clear from the reference in a Latin poem by Claudian (late 4th century), who says magna levi detrudens murmura tactu . . . intonet, that is "let him thunder forth as he presses out mighty ...

The first was the Denis d'or stringed instrument, [5] made by Václav Prokop Diviš in 1748, [6] with 700 electrified strings. In 1760, Jean Baptiste Thillaie de Laborde introduced the clavecin électrique , an electrically activated keyboard without sound creation.
During the remaining years of the 17th century, Cristofori invented two keyboard instruments before he began his work on the piano. These instruments are documented in an inventory, dated 1700, of the many instruments kept by Prince Ferdinando.

[2] Historically, it was mostly used as a practice instrument and as an aid to composition, not being loud enough for larger performances. [2]
Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell , or activating an electronic circuit (synthesizer, digital piano, electronic keyboard).
The New Grove musical dictionary summarizes the earliest historical traces of the harpsichord: "The earliest known reference to a harpsichord dates from 1397, when a jurist in Padua wrote that a certain Hermann Poll claimed to have invented an instrument called the 'clavicembalum'; [1] and the earliest known representation of a harpsichord is a sculpture (see below) in an altarpiece of 1425 ...
