The claviorganum is a combination-instrument from the Renaissance and Baroque times that connects a positive tracker organ to a stringed keyboard instrument. Harpsichord or virginal as well as a square piano are possible partners to the organ. Several historical examples still exist in divers collections of musical instruments within Europe or world-wide. In the first place serving Continuo demands it is provided to be prominent in soloist parts by its solemn sound, too.

We would like to introduce a small II-manual model linking an Italian disposed organ of three ranks to an Italian harpsichord of two ranks to you. It offers the opportunity to vary the brittle transparency of the harpsichord and the warm and full sound pattern of the organ just as to melt both to a new timbre by a manual coupler.

By the harpsichord being simply plugged up , both parts can easily be devided in means of solo use (or as a duet) or transportation. The demand for different pitches and temperments in ancient music is regarded to by a transposing mechanism and large-scale tuning applications.


The disposition:

I – manual organ:

I Gedackt 8´, pear/spruce
Bass and descant; foundation of plenum, smooth accompaniment
register

II Flute 4´, pear/spruce
Bass and descant; cubic open for a brightly drawing of the organ
passages

III Principal 8´, 75% tin
Descant; alternative 8´-basis that can be tuned as a Voce
Humana as well

II- manual harpsichord:

I 8´ Principal, brass

II 8´ Nasat, brass (also available as 4´)

Characteristics:
- Keyboards covered with boxwood and ebony
- Light and precise action
- Organ- and harpsichord-stops easily accessible on the bass side
- Shove coupler
- Quiet blower and pressure stable bellow combined in the seat
- Organ case made from pear, harpsichord from cypress - both with
high quality historical amber finish
- Temperature and humidity resistant wind chest
- Easy to transport in three parts, plugged in a few minutes

Of course we offer to build claviorgani in different regional constructions - as there are Flemish, French and German traditions – and deviating disposition and number of ranks, too.
