The piano was invented by the Italian musician and instrument maker Bartolomeo Cristofori (1655-1731) in Florence, Italy, around the year 1700. Cristofori's invention involved a new mechanism known as the "piano e forte" mechanism, which allowed the player to control the volume and dynamics of the sound by varying the force applied to the keys.
Cristofori's invention was initially called the "gravicembalo col piano e forte," meaning "harpsichord with soft and loud." Over time, the name was simplified to "pianoforte" and eventually shortened to "piano." Cristofori's early pianos were highly regarded and admired by musicians and composers of the time, but it took some time for the instrument to gain widespread popularity and use.
