Clavicytherium

William Horn Harpsichords

Harpsichords William Horn A CLAVICYTHERIUM is a harpsichord with the soundboard and strings mounted vertically.

A rather rare instrument, but very interesting. You can admire it in the beautiful engraving of Michael Praetorius (Syntagma Musicum) which is the opening image of our site.

The main advantage of a clavicytherium is to have the sound source facing the player (similar to what happens in a pipe organ).


The action converts the vertical movement of the keys in the horizontal movement of the jacks. The instrument takes up little space (less than a spinet), obviously you must have a vertical space of over 280 centimeters.

The instrument in the photo is inspired by an original by Albert Delin (Tournai, 1752) regarding the action, while the sounboard is inspired to a Ruckers harpsichord. The decoration of the soundboard is a copy after Andreas Ruckers (Castello Sforzesco, Milan).

All models of harpsichords, both single and double manual, can be built as a “clavicytherium”.

The weight of the keys remains unchanged in comparison with the traditional version, because the return of the jacks is obtained without any springs, using only the weight of the action levers.
