The development of the upright grand versions of pianos in the 18th-19th centuries was spurred by the need to reduce the space taken by the
grand pianos, at the time about 2.5 by 1.5 meters; the size of more compact
square pianos was also increasing. Vertical design, with the
soundboard oriented toward audience, allowed to produce full sound in аn instrument with a smaller footprint. The idea of a vertical placement of strings is very old:
clavicytherium, an upright version of the
harpsichord, was known as early as 1480. The first upright hammer-action grand piano was constructed in Italy by in 1739. The development then shifted to
Vienna, with
Christian Ernst Friederici creating the first
pyramid piano in 1745. After a hiatus, the uprights experienced a renaissance in Austria in the early 19th century (Seuffert, Wachtl, Bleyer) with significant contributions by
Christoph Ehrlich in Germany. The instruments featured two to six pedals, controlling the
piano,
sustaining,
bassoon-register, and sometimes "
janissary" (drum and bells) functions (Friederici also used
hand stops). The
lyre piano, made popular by in 1820s was the last iteration of the upright grand piano design. ==Gallery==
