Biography and projects

TransparenceS, the Glass Orchestra, was founded in 1988 by Jean Claude Chapuis, musician and science historian, and is the fruit of historical and musical research. Some of the orchestra’s objectives are as follows:

- rediscover and let others know about the repertoire of glass instruments (glass harmonica, seraph, euphone, glass chord piano, …)
- explore new sound horizons while also creating new instruments based on the acoustic richness of the glassmaker’s materials, and mixing their tones with those of other instruments and with vocals.
- explore the ensemble of the artistic potential of glass (plastic arts, image arts and other live show disciplines…)
All this knowledge and expertise explored and implemented by the individuals and workers of the orchestra stimulates inter-disciplinary activities, combining live shows, plastic arts and integrating responses that may exist in parallel connecting domains.

The team

The great potential of this instrumental ensemble and its capacities to explore new worlds depends on a team of high level professionals, who have enriched their artistic prowess with a varied range of professional development: coming from the domains of chamber and symphonic music, the jazz world, oriental and African music, musical teaching - percussion, piano, musical harmony and theory. Lighting technicians, specialists in light and the live show music hall experience; professionals and technicians involved in stage and movie soundtracks; glass professionals, for hot and cold working; directors of concert halls and theatres; mechanics and electrical engineers.

Combining the above expertises allows technical achievements and artistic creations to be led in a harmonious, concerted and inventive manner, with a wide scope of approaches.

Alain Clément

Régie Lumières


altAfter having drifted for several years in the teaching world, he decided it would definitely be much more fun on the stage?. He was right: at the Lucarne Theatre, where he came across his clown and various other characters, all this while working on miles of electric cables.
Then, a period at Philippe Genty, where he was to discover visual, sound and bodily material. Twelve years of splendid peregrinations.

Then back down to earth. Upon meeting Jean-Luc Pali: He ventured to the other side of the fence and took on the opposition with the Influences company, where he is employed as technical manager.
Guided by creations, and meetings like that with a certain Jean-Claude Chapuis and his world. There where the beauty of materials vies with the originality of sounds.
