Wiktionary

piano(Noun)
A keyboard musical instrument, usually ranging over seven octaves, with white and black keys, played by pressing these keys, causing hammers to strike strings.
piano(Adjective)
Soft. Used as a dynamic directive in sheet music in its abbreviated form, {p.}, to indicate lowering the volume of the music. In the pianoforte this is done by pressing the instrument's keys more lightly.

Origin: Short form of pianoforte, from piano + forte. So named because older keyboard instruments, notably the harpsichord and the clavier, could not produce varied volumes.
