Grand piano
From Wikipedia, the free encyclopedia
A grand piano is the concert form of a piano. A grand piano has the frame and strings placed horizontally, with the strings extending away from the keyboard. Grand pianos are distinguished from upright pianos, which have their strings and frame arranged vertically.
Grand pianos vary greatly in length. Those typically used for concerts and concert hall performances are 9 feet (274 cm) long. The shortest are less than 6 feet (180 cm) and frequently referred to as a baby grand or parlor grand. Longer strings and soundboard are primary features contributing to a higher-quality tone.
