During a visit in 1492 when Emperor Maxemilian in Strasbourg, reported a Venetian ambassador "... He let the pipes simultaneously resound with the strings or he only played the pipes. Then he sat down again and it sounded just the strings. With this sweet exchange he took the interests of all caught and all were paralyzed with pleasure and outraged ... ".
127 years later Paul Wissmayer in Nuremberg built a hexagonal Virginal in Italian design to a chest organ from Stefan Cuntz and took the two instruments to a two-manual Claviorganum together. Unfortunately, this instrument is only the cover of the virginal condition, on the inside the whole Claviorganum is detained in a painting.
These two from the concept of producing sound forth as different instruments tolerate not only next to each other, they complement each sound so good that they-as already noticed in 1492, may be coupled with a convincing effect. From the Renaissance, the first notes and instruments originate. As with any tool, there were times of prosperity and times where it almost forgotten. But his track leads up in the romance (Liszt) and present (JN David) where composers and musicians could build Claviorganen. In the Archbishop's Treasury Salzburg one of the few surviving instruments can be visited and occasionally to hear. The charm and the quality of Claviorganums lie in the opportunities that arise from the sound juxtaposition and blending of the two instruments.

The Claviorganum may be regarded as a positive organ with the special additional register Spinetto. The special registers are so common in organ building - think of chimes, Vogelsang or Tremulant; the harpsichord sound, however, is much more frequently used than the above special registers. The organ literature is betrachet can learn through the harpsichord sound enrichment and vice versa. A church musician, often formed on both instruments will know welcome in any case, and to use the possible combinations. From this perspective, the Claviorganum the ideal continuo instrument for small or larger ensembles. As a continuo instrument, it may, for example, in an oratorio by the same player as positive organ, harpsichord or coupled. This results in new, surprising possibilities for players and concert goers. Genuine his sound stimulus shows both solo pieces of the Renaissance, Baroque, as of modernity are to bring their diverse soundscapes well to lecture and distinctive combinations win a lot of expressiveness.
