I enjoy playing piano a lot. It is an acoustic , stringed instrument
I don't believe a piano is a stringed instrument. Perhaps you meant guitar?
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
during his time performing with Pigface. It has appeared on 18 albums. It was described by Pigface vocalist Chris Connelly as "a large rail-way sleeper with piano wire which was stretched over the guitar so that it could be played..." Sonic Boom Magazine stated "The Anti Tank Guitar...has made Lab Report more of an acoustic terrorist movement than a band since their inception." The instrument is a large stringed instrument capable of producing everything from the mimicked sounds of guitar and bass to monstrous percussive blows. Veteran
