The damper, or loud pedal, raises all the dampers so that all the strings struck continue to vibrate even after the keys are released. The soft pedal either throws all the hammers nearer to the strings so that the striking distance is diminished by one-half, or shifts the hammers a little to one side so that only a single string instead of the two or three is struck. Some pianos have a third, or sustaining, pedal that does not raise all the dampers, but keeps raised only those already raised by the keys at the moment this pedal is applied. The use of these pedals can produce subtle changes in tone quality. Many upright pianos have been built in which the application of a pedal interposes a strip of felt between the hammers and strings so that only a very faint sound is produced. According to the shape of the case, pianos are classified as grand, square, and upright. The square form (actually rectangular) is no longer built. For use in private homes it has been entirely superseded by the upright, which takes up far less room. Grand pianos are built in various sizes, from the full concert grand, 2.69 m (8 ft 10 in) long, to the parlor or baby grand, less than 1.8 m (6 ft) long. Upright pianos include the late 19th-century cottage piano, of which the upright grand is merely a larger form. The modern spinet and console pianos are small uprights related to the cottage piano. In the upright pianos the strings run vertically, or diagonally, from the top to the bottom of the instrument. Uprights and small grands are sometimes overstrung; that is, the bass strings are stretched diagonally across the shorter treble strings, thereby gaining extra length and improved tone quality. The combined tension of the strings on a concert grand piano is about 30 tons, on an upright about 14.
