The tangent would be brought into contact with all three strings simultaneously through a rotation. Gerbert's keys have been interpreted as revolving bars with a long "spatula" tangent placed under the strings. manuscript, now lost, in Saint Blaise monastery. In search of a different solution, I found myself reconsidering two objects that are certainly of the first level.Ī.) The only drawing of the keyboard that we have left, complete with indications on the scale and on the structure of the keys, is the one copied by Martin Gerbert from a 12th c. Instruments made following these hypotheses have little use in the performance of medieval music. There are 12 keys within the octave, the first of which should be the nut : they are definetly too many, unless you want to conclude that this is a chromatic keyboard.Īnother arbitrary element lies in the choice of the generally adopted fifth and octave tuning, inspired by the organum parallelum polyphonic technique, described in texts that precede any known depiction of the Organistrum by at least a century or two.

This obviously concerns the Variable elements and the Unknown Elements.Īlmost all the replicas take as a model the Organistrum of the Portico de la Gloria of Santiago de Compostela because, compared to all the other representations it is the richest in details, it has the maximum number of keys, it occupies the most important location. We know nothing more about the inner structure of the keyboard.įrom these premises it follows that the replicas of the Organistrum so far attempted are at least partly hypothetical. The same drawing gives an idea of the possible mechanism of the keys. There is no information about the tuning and the musical scale but from a plate in Martin Gerbert, De cantu et musica sacra, 1774. The number of keys can change: 6 to 11 (or 12). The row of keys ends within the middle of the string.The wheel and the crank are a characteristic element, as are the three strings, in one case two, in one other perhaps one.The dimensions are such as to occupy the knees of two men seated side by side.The Organistrum has an « 8 » shape, with a rectangular extension.The information we have on the instrument comes from a dozen images in books and works of art of the 12th century.

The aim of the present article is to present the ultimate result of my research on the possibility of rebuilding the Organistrum (Giuseppe Antonio Severini, Organistrum.
