What is "lautenwerck"

The lautenwerck (also spelled lautenwerk), or lute-harpsichord (lute-clavier), was a European keyboard instrument of the Baroque period. It was similar to a harpsichord, but with gut rather than metal strings, producing a mellow tone.

The instrument was favored by J. S. Bach, who owned two of the instruments at the time of his death, but no specimens from the 18th century have survived to the present day. It was revived in the 20th century by harpsichord makers Willard Martin, Keith Hill and Steven Sorli. Two of its most prominent performers are the early music specialists Gergely Sárközy and Robert Hill.
