In 1579 the refugee Antwerper Lodovicus Theewes made a claviorganum for Sir Anthony Roper, a recusant Catholic courtier and grandson of Sir Thomas More, who lived at Farningham Manor in Kent. Visitors included Thomas Tallis and William Byrd. The remains of the instrument survive in the Victorian & AlbertMuseum. The harpsichord is the oldest surviving outside Italy. The organ is the only survivor of a type which must have been common in the courts of 16th century Europe. Henry VIII possessed several, described as ‘regals’. Philip van Wilder made an inventory of Henry’s musical instruments in 1547; this one might have been described as “an Instrumente with a double Virginall and a double regall with iij stopped of pipes of woode … with a foote of wainscott and the Bellowes lyinge in the same.” The surviving parts are now in the Victoria and AlbertMuseum in London, where the case is on display. The organ parts consist of the wind chest and upperboards, a single wooden pipe (4ft D#), regal boots made of paper, and two bellows.
In 2005 Malcolm Rose made a reconstruction of the harpsichord for Dr Joseph Kung. Malcolm has also researched the history of the instrument. A detailed description of the instrument can be found in Malcolm Rose Further on the Lodewijk Theewes Harpsichord. Galpin Society Journal vol55 pp279-309 (2002 www.music.ed.ac.uk/euchmi/galpin). For the history of the instrument and its ownership see Malcolm Rose, The History and Significance of the Lodewijk Theewes Claviorgan. Early Music vol32/4 pp577- 593 (Nov 2004 www.em.oupjournals.org). For further information about the musical context see Terence Charlston, An instrument in search of its repertoire?

In 2008 we made a reconstruction of the organ for Joseph Kung. It has the following stops:
8ft regal, with wood resonators, and paper boots
4ft, 2ft and 1ft open wood stops, made of oak
¼ft cymbal, open metal, repeating an octave every octave
birdsong and tremulant
The key compass of the harpsichord is C – c³ 49 notes, and of the organ C, D – c³ 48 notes, divided at bº/c¹. The organ is played from the harpsichord keys. A register can disengage the organ stickers so that the harpsichord can be used alone. The harpsichord registers can all be moved off so that the organ can be used alone. So the organ and harpsichord can be played on their own, or together in consort. The pitch, from the surviving 4ft D# pipe, is A410Hz, the tuning ¼ comma meantone.
