<P> The Shudi firm was passed on to Shudi's son - in - law John Broadwood, who adapted it to the manufacture of pianos and became a leading creative force in the development of that instrument . </P> <P> German harpsichord makers roughly followed the French model, but with a special interest in achieving a variety of sonorities, perhaps because some of the most eminent German builders were also builders of pipe organs . Some German harpsichords included a choir of 2 - foot strings (that is, strings pitched two octaves above the primary set). A few even included a 16 - foot stop, pitched an octave below the main 8 - foot choirs . One still - preserved German harpsichord even has three manuals to control the many combinations of strings that were available . This represents the northern school of German harpsichord building as featured by builders such as Hieronymus Hass and Christian Zell . The southern school features instruments inspired by Italian harpsichord building: simple large double manual instruments, often undecorated, using brass strings and an Italian construction of the soundboard . These instruments were built by Michael Mietke, Heinrich Gräbner and the Silbermann family . Many modern builders have copied the Mietke instruments and they have proven to be an alternative to the French type harpsichord . </P> <P> At the peak of its development, the harpsichord lost favor to the piano . The piano quickly evolved away from its harpsichord - like origins, and the accumulated traditional knowledge of harpsichord builders gradually dissipated . The old harpsichords were not valued, often destroyed (for example, they were used in the Paris Conservatory for firewood), and the instrument was something of a ghost for the duration of the 19th century . One exception is the continued use for recitative music in opera well into the 19th century, the fact that it did not completely disappear from the public eye played a role in revival efforts that began in the mid-19th century . However, by the late 19th century, despite revival efforts, its use even in the recitative style began to disappear . </P> <P> Interest reawakened around the dawn of the 20th century, and the harpsichord was gradually revived . </P>
