This replica of a 1670 triple-fretted clavichord of Israel Gellinger in Frankfurt was built by Jack Peters of Seattle, Washington ( http://www.jackpeters.com ).
The replica of Johann Andreas Stein's 1787 unfretted, single-strung clavichord, based on the one in The Hague Gemeentemuseum, was built by Jack Peters of Seattle ( http://www.jackpeters.com ). About this instrument, Jack Peters writes:
"An atypical single strung historical clavichord. The piano maker Stein was known for his ingenious inventions, including the "Melodica" and the "Saitenharmonica". Starting as an organ builder he evolved into a celebrated fortepiano maker to the Mozarts. His late, 1787, 54-note (C-f3) clavichord in the Hague Gemeentemuseum is a model of compactness and restraint. Not only short but also very narrow, the stringband is squeezed onto a tiny bridge and soundboard. The sound is surprisingly Viennese-pianolike and its extended treble allows the music of late composers like Haydn and C.P.E. Bach. John Koster, in his article inDe Clavichordio I, points out the great differences between it and the earlier Mozart clavichord now in the Hungarian National Museum (1762). Wound strings are critical to the success of the bass octave, as are the heavy iron and phosphor bronze for the single strings of the treble. The extremely narrow tangents must be regulated with great precision." ---- Jack Peters replicator and builder in Seattle.
