Piano - a musical instrument classified as a struck chordophone, invented in 1709 with a hammer mechanism and keys. The inventor?s name was Bartolomeo Cristofori, an Italian from Padua who lived in the 18th century. His invention has its roots in the clavichord and, partially, the harpsichord. In a modern piano, the strings are cross-strung on a metal board in threes for high and mid sounds and in twos for the low sounds. Single strings are responsible for producing the lowest tones.
