The Instruments we play

Harmonicas (Glass harmonicas)


The instrument, invented by B. Franklin in 1761, originated from the seraph. With this invention, it became possible to achieve more complex chords. Very fashionable from around 1768 onwards on "the old continent ", the greatest composers and classical and romantic poets, sensitive to its ethereal tones, became huge fans.
The performer vibrates crystal parts (which go into motion when subjected to a rotational movement) by rubbing them with moistened fingers.


Entitled "Verillon" in the Diderot Encyclopaedia. This set of 56 drinking glasses was the height of fashion from the first half of the 18th century onwards. The composer C. W. Gluck created a virtuoso piece for it that was appreciated throughout Europe

Crital bachet. Euphone

Invented in the 18th century by the great acoustician Chladni, metal rods are made to vibrate by glass rods. Of exceptional purity, the notes of the euphone combine particularly harmoniously with the seraph and the harmonica.


A chromatic set of 48 crystal bells.


A keyboard instrument where hammers strike "cords" of glass, which resembles the celesta, and the "sparkle" of its tones are only equalled by those of its chords. It has a range of 5 octaves.

Cut-glass cimbalom

A vibraphone made with crystal keys.


A set of 36 chromatic notes. Their ethereal resonances open up musical pieces toward distant and dreamlike horizons.

Bass Marimba

A low register octave, made with crystal keys.


Comprising 6 octaves, its clear and brilliant tone is reminiscent of the music of church bells.


Ancestor of the moog (cousin of the Martenot waves). This rare instrument, invented by the engineer Théremin at the start of the 20th century, happily combines its subtle, illuminating (and uncanny) melody with the orchestra’s airy tones


Crystal keys achieving 3 chromatic octaves. The instrument is reminiscent of the deep and rhythmic sounds of Africa and the Caribbean.

"Glass harp"

The result of acoustic research carried out in the 18th century. Here (as with the other instruments), the gracefulness of gesture during execution and the architecture of the object contribute perfectly to the delicateness of its sound.

"Gamelan" Glass organs

One produces sound from glass, the other of air columns


Set of glass tubes tuned over 3 chromatic octaves, for an Asian-bound sound.


30 columns of air are made to vibrate by percussion. This "rhythmic and melodic" instrument is the "double bass" of the TransparenceS Ensemble.

Various other forms of percussion:

A set of 15 triangles, maracas, large bells, Chinese chimes, chimes, rain sticks...


The ancestor of this instrument, which was known as the "Chemical harmonica" was perfected by Kastner midway through the 19th century. The air columns contained in the glass tubes are made to vibrate by the flames.

Other more traditional and familiar instruments are also used:
The human voice, musical saw, chord harp, spinet, bandoneon, harmonium...
