The harpsichord was largely obsolete, and seldom played, during a period lasting from the late 18th century to the early 20th. The instrument was successfully revived during the 20th century, first in an ahistorical form strongly influenced by the piano, then with historically more faithful instruments. The revival was the joint work of performers, builders, and composers who wrote new harpsichord pieces.
In the earlier stages, 20th-century harpsichords were heavily influenced by the technology of the modern piano, and usually included metal framing (which was entirely absent in historical instruments). It was felt that such construction would increase the stability of tuning. Since heavy framing tends to stifle harpsichord sound, instruments were bolstered by other means, notably the addition of a 16' stop (an additional set of strings that played an octave below normal pitch); such stops were somewhat unusual in the historical period but became widespread in the first half of the 20th century. An example was the harpsichord produced by Pleyel et Cie at the request of Landowska.
Starting in the mid-20th century, instruments were introduced whose construction followed historical principles, with thinner cases, historical dispositions (arrangements of choirs of strings) and no metal framing. Among the leaders of this shift were Frank Hubbard, William Dowd, and Martin Skowroneck. With time, such instruments came to dominate the scene, and the older heavy-frame instruments are almost never manufactured today. They retain historical value, however, since they were the instruments that early to mid-20th-century composers had in mind when they wrote their works.
The transition of harpsichord building toward historicist principles is covered in detail by Hubbard (1965), Zuckermann (1969), and Kottick (2003), cited below.
Among the performers who propelled the revival of the harpsichord have been the following (listed by date of birth):
Landowska and also Elisabeth Chojnacka (1939- ) achieved particular reputations for the performance of new music for the harpsichord.
In the 20th century, classical composers returned to the harpsichord as they sought out variation in the sounds available to them. Under the influence of Arnold Dolmetsch, the harpsichordists Violet Gordon-Woodhouse (1872–1951) and in France, Wanda Landowska (1879–1959), were at the forefront of the instrument's renaissance.
