My research has led to the creation of a new type of keyboard with keys moving by swinging.
This keyboard avoids the disadvantages of traditional system with sliding keys, it allows a number of melodic string more important.
The sliding keyboard was invented in the 11th century and then improved in 18th (chromatic keyboard).
Why the vielle could not continue its evolution today?
Should we still play keyboards as they were invented at the time of
With this new keyboard, I can install up to 10 melodic strings with a wheel with a diameter of 200mm, or 6 with a 160mm wheel.
Why so many melodic strings?
The abundance of melodic strings can increase the play opportunities for greater variation, creativity and musicality.
-timbre variation and fixed chords: by using strings of different materials and tensions or by making chords between melodic strings.
-vary the keys: changing melodic strings in place to facilitate change of tone, without changing the fingering.
-tapping: on models of electric or electroacoustic vielles, strings can be simply struck by the jacks, and this sound can create an accompaniment with other melodic strings in contract with the wheel.
-variable chords: a good technic I experimented is the removing of jacks (photo at right) on two identical strings (harmonic melodic strings). By removing one jack on two, it is possible to do all chords with several odd semitones (half-tone, minor thirds, fourths, fifths, sixths...) are allowed.
For the achievement of the resonance box, the models painted by Georges de la Tour were my first inspiration, but also was the Jean-Luc Bleton's approach presented by (in “vielle à roue - territoires illimités” edition FAMDT). Thus, I chose to carry out and arched bottom (it fits in cylinder) and a symmetrical convex table, the whole made out of maple. The system of double maple arches allows a better rigidity of the ensemble, therefore it limits the inner reinforcement, and thus it release and amplify vibrations of the bottom. What produces a better sound quality.
Sound electric treatment
I propose 3 levels of sound according to your needs:
Acoustic sound system:
You want one or two microphones that capture the best natural sound environment of the instrument: For this I propose a aerian Lavalier micro placed on the wheel cover, or a Schertler DYN placed on the surface of the table or the bottom. This microphone can be doubled to produce a stereo output.
Electroacoustic sound system:
The sound is captured at the source, in the brigges closest to the strings. Depending on the complexity of the instrument, there will be 3 to 5 (or more) sensors. I use Schertler STAT (excellent quality sensors ) or Piezo sensors of good quality.
Elec model is designed to be played amplified, with 3 or 4 sensors

making variable chords, with one jack on two.

Quick Change String
On this view of expert model, one can see a bridge equipped with lifting systems and screws used to adjust the string pressure on the wheel. At the other end, the nuts are also equipped to move forward and backward strings. Thus the strings not used can not be affected by the jacks. Objective: maintain contact with only the playing strings, for more precision and flexibility of play.
2 outputs for the melodic strings
The advantage of using two bridges, is to differentiate the sound treatment for two melodic strings groups. In addition the sound processing will allow to achieve a natural stereo effect.
creativity of the medieval luthiers is very amazing, and
whose inner workings are still very mysterious. Already done, the
reconstruction of the vielle painted by Georges de la Tour is my first
work in this direction. The biggest challenge was to imagine parts of
the instrument not represented by the iconography.

Other project: a symphony reconstructed according several sources (for example MS Psalterio Luttrel 1325 below). I tried to design the keyboard as it was during the middle age and not to insert a keyboard as it was invented during 18th century.
