“Pianoforte” means “The soft-loud instrument” in contrast to the harpsicord
Most piano players are aware that the piano's modern name is actually a shortened version of its original name, "pianoforte," which is a compound of the Italian words for "soft" and "loud." This name was given to the new instrument in order to differentiate it from its forbear instrument, the harpsichord, whose volume range is far less flexible than that of the piano.
While earlier instruments such as the harpsichord generate sound by plucking strings, the piano was the first instrument to successfully generate sound by striking strings. Invented around 1700 by the Paduan instrument-maker Bartolomeo Cristofori, the revolutionary mechanism of the piano, with hammers that return to the rest position immediately after striking, made possible a far greater degree of control and nuance than previous instruments.
