Piano is a large keyboard musical instrument invented in Italy by Bartolomeo Cristofori. It has a wooden case enclosing a soundboard and metal strings, which are struck by hammers when the keys are depressed. The strings’ vibration is stopped by dampers when the keys are released and can be regulated for length and volume by two or three pedals. The word piano is a shortened form of pianoforte, the Italian term for the early 1700s versions of the instrument, which in turn derives from gravicembalo col piano e forte and fortepiano. There are two main types of piano: the grand piano and the upright piano. The grand piano is used for Classical solos, chamber music and art song and it is often used in jazz and pop concerts. The upright piano, which is more compact, is the most popular type, as they are a better size for use in private homes for domestic music-making and practice.
