Piano
The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. 
The word piano is a shortened form of "pianoforte", the Italian term for the early 1700s versions
.
The fortepiano, the fore-runner of the modern Piano, was invented by Bartolomeo Cristofori in Florence around 1725, and soon replaced the harpsichord as a solo and ensemble keyboard instrument.
The family of stringed instruments, consisting of the violin, viola, cello and contrabass evolved in Italy in the mid 16th century. Antonio Stradivari, Andrea Guarneri, Nicolo Amati and other master instrument makers crafted stringed instruments that were highly prized, widely imitated, but never equaled.
