Jan Couchet the Elder was the grandson of the famed Flemish keyboard maker Hans Ruckers. Couchet carried on the Ruckers tradition, inheriting the workshop of Ruckers's eldest son in 1643. This harpsichord originally had only one keyboard and one set each of unison and octave strings. In the eighteenth century the case was lengthened and a second keyboard and a second set of unison strings were added. The number of rows of jacks was increased from two to four: a close-plucking "lute stop" that plucks one set of unison strings from the upper keyboard, a second row that plucks the other set of unison strings and is operated from both keyboards, a third row that plucks the octave strings, and a fourth row that plucks the same strings as the lute stop. Both the first and the fourth rows divide at middle C, so that it is possible to play the lute stop in the treble from the upper keyboard while playing the farthest unison in the bass from the lower keyboard or vice versa.
