Mécanophonie is a musical installation that is an exhibition of instruments and automated devices, created by Denis Brély. Although in Mécanophonie we can find "normal" instruments, such as barrel organs, bass drums, drums, cymbals and pianolas, violins or xylophones, Mécanophonie is a collection of gadgets in which the premise is that everything moves, mechanically, and everything sounds. Levers, gears, bellows, rails, hanging mobiles, bells, toys, domino effects, spirals, electrical impulses? A carrousel of objects, many of them everyday, all of them evocative, to immerse us in a magical atmosphere that takes us back to childhood, to that attic full of strange artefacts that now, thanks to Mécanophonie, come to life to create suggestive and strange symphonies.
