Model: Leipzig Henkel cat. No.3 1540

Earliest extant clavichord, kept at Leipzig University Musical Instrument Museum. Repertoire is limited to the pieces of this period, as some of the notes are 4-fretted.

Compass: GG-d'''

Size:1268mmW x375mmD x 85mmH
Reference: Drawings by
Ute Singer, 1976
Model: Johann Jacob Donat, 1700

The original compass of C to c''' is extended to GG to d'''. GG is located next left to C and AA/HH are on the back of the split sharp keys of C#/Eb. The sound board bridge stretches very close to the spine and the sound board is sandwiched between the bridge and the liner. It seems to effectively contribute to nicely spread the high frequency sound energy to whole body of the instrument.

Compass: C - f'''

Size: 1295mmW x 365mmD x 116mmH
Reference: Drawings by Richard N. Loucks, 1981

Model: Christian Gottlob Hubert, 1784
Presently, four clavichords made by C. G. Hubert in 1784 are found (K. Vermaiji). The original instrument, on which this replica was made, is the one kept in Edinburgh.  Other three clavichords made in the same year are also fretted type, but all of them have the compass of C to g'''.  There are no stabilizing braces on the baseboard. which are often seen in similar type of instruments.
